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.

* c-decl.c (implicit_decl_warning): Use add_fixit_replace

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’?

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
- <<< RED

Always support float128 on x86.
In <https://gcc.gnu.org/ml/gcc-bugs/2016-08/msg03233.html>, Nick
reported i386-elf and ia64-elf failing to build because of
float128_type_node being NULL, but being used by the back end for
__float128.
The global float128_type_node is only available conditionally, if
target hooks indicate TFmode is not only available as a scalar mode
and of the right format, but also supported in libgcc. The back-end
support, however, expects the type always to be available for
__float128 even if the libgcc support is missing.
Although a target-specific node could be restored in the case where
libgcc support is missing, it seems better to address the missing
libgcc support. Thus, this patch enables TFmode soft-fp in libgcc
globally for all x86 targets - the only special cases needed being for
targets that use soft-fp for SFmode and DFmode, one of which already
had the support for TFmode as well (so I based the i[34567]86-*-rtems*
configuration on that present for i[34567]86-*-elfiamcu). The i386
implementation of TARGET_LIBGCC_FLOATING_MODE_SUPPORTED_P is then
removed as no longer needed.
I can provide such a patch for ia64 if useful, but am not in a
position to test it (and while I'm reasonably confident that enabling
this support would be right for ia64-elf and ia64-freebsd, I've no
real idea if enabling libgcc support for TFmode, with or without also
enabling it for XFmode, would be safe for ia64-vms).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

Drop excess size used for run time allocated stack variables.
* get_dynamic_stack_size is passed a SIZE of a data block (which is
allocated elsewhere), the SIZE_ALIGN of the SIZE (i.e. the alignment
of the underlying memory units (e.g. 32 bytes split into 4 times 8
bytes = 64 bit alignment) and the REQUIRED_ALIGN of the data portion
of the allocated memory.
* Assuming the function is called with SIZE = 2, SIZE_ALIGN = 8 and
REQUIRED_ALIGN = 64 it first adds 7 bytes to SIZE -> 9. This is
what is needed to have two bytes 8-byte-aligned at some memory
location without any known alignment.
* Finally round_push is called to round up SIZE to a multiple of the
stack slot size.
The key to understanding this is that the function assumes that
STACK_DYNMAIC_OFFSET is completely unknown at the time its called
and therefore it does not make assumptions about the alignment of
STACKPOINTER + STACK_DYNMAIC_OFFSET. The latest patch simply
hard-codes that SP + SDO is supposed to be aligned to at least
stack slot size (and does that in a very complicated way). Since
there is no guarantee that this is the case on all targets, the
patch is broken. It may miscalculate a SIZE that is too small in
some cases.
However, on many targets there is some guarantee about the
alignment of SP + SDO even if the actual value of SDO is unknown.
On s390x it's always 8-byte-aligned (stack slot size). So the
right fix should be to add knowledge about the target's guaranteed
alignment of SP + SDO to the function. I'm right now testing a
much simpler patch that uses
REGNO_POINTER_ALIGN(VIRTUAL_STACK_DYNAMIC_REGNUM) as the
alignment.
