C: Fix missing spaces in 'struct' fix-it hints

In r237714 I added fix-it hints to the C frontend for missing "struct"
keywords e.g.:

spellcheck-typenames.c:69:1: error: unknown type name ‘foo_t’; use
‘struct’ keyword to refer to the type
 foo_t *foo_ptr;
 ^~~~~
 struct

However when using the (not yet in trunk) option
 -fdiagnostics-generate-patch,
the generated patch is nonsensical:

  -foo_t *foo_ptr;
  +structfoo_t *foo_ptr;

Fix the fix-its by adding a trailing space to each one, giving:

  -foo_t *foo_ptr;
  +struct foo_t *foo_ptr;

* c-parser.c (c_parser_declaration_or_fndef): Add trailing space

diagnostic-show-locus.c: handle fixits on lines outside the regular ranges

The diagnostic_show_locus implementation determines the set
of line spans that need printing based on the ranges within the
rich_location (in layout::calculate_line_spans).

Currently this doesn't take into account fix-it hints, and hence
we fail to print fix-it hints that are on lines outside of
those ranges.

This patch updates the implementation to take fix-it hints into
account when calculating the pertinent line spans, so that such fix-it
hints do get printed.  It also adds some validation, to ensure that
we don't attempt to print fix-its hints affecting a different source
file.

Remove arbitrary limits from rich_location

This patch eliminates the hard-coded limits within rich_location
(up to 3 ranges, up to 2 fixits).  The common case is still
handled by embedding the values inside rich_location - it only
uses dynamic allocation if these limits are exceeded, so
creation of rich_location instances on the stack should still
be fast.  This is implemented via a new container class,
semi_embedded_vec <T, N>.

runtime: use -fgo-c-header to build C header file

    Use the new -fgo-c-header option to build a header file for the Go
    runtime code in libgo/go/runtime, and use the new header file in the C
    runtime code in libgo/runtime.  This will ensure that the Go code and C
    code share the same data structures as we convert the runtime from C to
    Go.

    The new file libgo/go/runtime/runtime2.go is copied from the Go 1.7
    release, and then edited to remove unnecessary data structures and
    modify others for use with libgo.

    The new file libgo/go/runtime/mcache.go is an initial version of the
    same files in the Go 1.7 release, and will be replaced by the Go 1.7
    file when we convert to the new memory allocator.

    The new file libgo/go/runtime/type.go describes the gccgo version of the
    reflection data structures, and replaces the Go 1.7 runtime file which
    describes the gc version of those structures.

    Using the new header file means changing a number of struct fields to
    use Go naming conventions (that is, no underscores) and to rename
    constants to have a leading underscore so that they are not exported
    from the Go package.  These names were updated in the C code.

    The C code was also changed to drop the thread-local variable m, as was
    done some time ago in the gc sources.  Now the m field is always
    accessed using g->m, where g is the single remaining thread-local
    variable.  This in turn required some adjustments to set g->m correctly
    in all cases.

    Also pass the new -fgo-compiling-runtime option when compiling the
    runtime package, although that option doesn't do anything yet.

rs6000: Don't emit a use of LR in returns and sibcalls

The exit block (to which every return artificially jumps) already has
a use of LR.  The LR use in all returns and sibcalls is an anachronism,
probably made unnecessary by the dataflow merge.  The simple_returns
that shrink-wrapping generates also do not have such a use.  Newer
backends do not do this either it seems.

With this use removed, a normal return is no longer a parallel but just
a return insn, and cfgcleanup then can transform conditional jumps to
those into conditional returns.

This splits the return emission code with restoring_FPRs_inline from
that without it; this is simpler code, fewer lines, and less indentation.

The return_internal_<mode> pattern can now be deleted since nothing uses
it anymore.

rich_location: add convenience overloads for adding fix-it hints

Adding a fix-it hint to a diagnostic usually follows one of these
patterns:
(a) an insertion fix-its, with the insertion at the primary caret location
(b) a removals/replacements, affecting the range of the primary location

(other cases are possible, e.g. multiple fix-its, and affecting other
locations, but these are the common ones)

Given these common cases, this patch adds overloads of the rich_location
methods for adding fix-it hints, so that the location information can
be omitted if it matches that of the primary location within the
rich_location.

Similarly when adding "remove" and "replace" fix-it hints to a diagnostic,
it's tedious to have to extract the source_range from a location_t
(aka source_location).  To make this more convenient, this patch
adds overload of the rich_location::add_fixit_remove/replace methods,
accepting a source_location directly.

The patch updates the various in-tree users of fix-it hints to use
the new simpler API where appropriate.  I didn't touch the case where
there are multiple fix-its in one rich_location, as it seems better to
be more explicit about locations for this case (adding a pair of parens
in warn_logical_not_parentheses).

The above makes the gcc_rich_location::add_fixit_misspelled_id overload
taking a const char * rather redundant, so I eliminated it.

compiler: add -fgo-c-header=FILE to create a C header

    The new -fgo-c-header=FILE option will write a C header file defining
    all the struct types and numeric const values in package scope.  This
    will be used when building the Go runtime package (libgo/go/runtime) to
    generate a C header file that may be included by the C code in the C
    runtime package (libgo/runtime).

    This will ensure that the Go code and C code are working with the same
    data structures as we convert the runtime from C to Go to upgrade to the
    current GC runtime, notably the concurrent garbage collector.

Add validation and consolidation of fix-it hints

The first aspect of this patch is to add some checking of fix-it hints.
The idea is to put this checking within the rich_location machinery,
rather than requiring every diagnostic to implement it for itself.

The fixits within a rich_location are "atomic": all must be valid for
any to be applicable.

We reject any fixits involving locations above
LINE_MAP_MAX_LOCATION_WITH_COLS.

There's no guarantee that it's sane to modify a macro, so we reject
any fix-its that touch them.

For example, note the attempt to provide a fix-it for the definition
of the macro FIELD:

spellcheck-fields-2.c: In function ‘test_macro’:
spellcheck-fields-2.c:26:15: error: ‘union u’ has no member named ‘colour’; did you mean ‘color’?
 #define FIELD colour
               ^
               color
spellcheck-fields-2.c:27:15: note: in expansion of macro ‘FIELD’
   return ptr->FIELD;
               ^~~~~

After this patch, the fixit is not displayed:

spellcheck-fields-2.c: In function ‘test_macro’:
spellcheck-fields-2.c:26:15: error: ‘union u’ has no member named ‘colour’; did you mean ‘color’?
 #define FIELD colour
               ^
spellcheck-fields-2.c:27:15: note: in expansion of macro ‘FIELD’
   return ptr->FIELD;
               ^~~~~

We might want some way for a diagnostic to opt-in to fix-its that
affect macros, but for now it's simplest to reject them.

The other aspect of this patch is fix-it consolidation: in some cases
neighboring fix-its can be merged.  For example, in a diagnostic to
modernize old-style struct initializers from:

 struct s example = {
- foo: 1,
+ .foo = 1,
 };

one approach would be to replace the "foo" with ".foo" and the ":"
with " =".  This would give two "replace" fix-its:

  foo: 1,
  --- FIXIT 1
  .foo
     - FIXIT 2
     =

This patch allows them to be consolidated into a single "replace" fix-it:

  foo: 1,
  ----
  .foo =

Tweak to colors of fix-it hints

Previous, fix-it hints were printed using the color of the severity
of the diagnostic (magenta for warnings, red for errors, cyan for
notes).

This patch updates fix-it hints so that replacement text is printed in
green, to better distinguish the suggested improvement from
the current code.  For example:

spellcheck-fields.cc:52:13: error: 'struct s' has no member named 'colour'; did you mean 'color'?
   return ptr->colour;  <<< RED
               ^~~~~~   <<< RED
               color    <<< GREEN

It makes sense for the underlinings that indicate deletions to
be printed in red, so the patch changes that also.  For example:

diagnostic-test-show-locus-color.c:179:9: warning: example of a removal hint
   int a;;  <<< MAGENTA
         ^  <<< MAGENTA
