Handle sibcalls with aggregate returns
We treated this g as a sibling call to f:
int f (int);
int g (void) { return f (1); }
but not this one:
struct s { int i; };

struct s g (void) { return f (1); }
We treated them both as sibcalls on x86 before the first patch for PR36326,

runtime: move schedt type and sched var from C to Go
This doesn't change any actual code, it just starts using the Go
definition of the schedt type and the sched variable rather than the C
definitions.
The schedt type is tweaked slightly for gccgo. We aren't going to
release goroutine stacks, so we don't need separate gfreeStack and
gfreeNostack lists. We only have one size of defer function, so we
don't need a list of 5 different pools.

Use rtx_mode_t instead of std::make_pair
This change makes the code less sensitive to the exact type of the mode,
i.e. it forces a conversion where necessary. This becomes important
when wrappers like scalar_int_mode and scalar_mode can also be used
instead of machine_mode.
Using rtx_mode_t also abstracts away the representation. The fact that
it's a std::pair rather than a custom class isn't important to users of
the interface.

bb-reorder: Improve compgotos pass (PR71785)
For code like the testcase in PR71785 GCC factors all the indirect branches
to a single dispatcher that then everything jumps to. This is because
having many indirect branches with each many jump targets does not scale
in large parts of the compiler. Very late in the pass pipeline (right
before peephole2) the indirect branches are then unfactored again, by
the duplicate_computed_gotos pass.
This pass works by replacing branches to such a common dispatcher by a
copy of the dispatcher. For code like this testcase this does not work
so well: most cases do a single addition instruction right before the
dispatcher, but not all, and we end up with only two indirect jumps: the
one without the addition, and the one with the addition in its own basic
block, and now everything else jumps _there_.
This patch rewrites the algorithm to deal with this. It also makes it
simpler: it does not need the "candidates" array anymore, it does not
need RTL layout mode, it does not need cleanup_cfg, and it does not
need to keep track of what blocks it already visited.

As we move toward the Go 1.7 garbage collector, it's essential that all

in Go code. This rewrites the code that converts from a Go type to a

arc/nps400: New peephole2 pattern allow more cmem loads
In the case where we access a single bit from a value and use this in a
EQ/NE comparison, GCC will convert this into a sign-extend and GE/LT
comparison.
Normally this would be fine, however, if the value is in CMEM memory,
then we don't have a sign-extending load available (using the special
short CMEM load instructions), and instead we end up using a long form
load with LIMM, which is less efficient.
This peephole optimisation looks for the sign-extend followed by GE/LT
pattern and converts this back into a load and EQ/NE comparison.

* config/arc/arc.md (cmem bit/sign-extend peephole2): New peephole

Fix locations within raw strings
Whilst investigating PR preprocessor/78324 I noticed that the
substring location code currently doesn't handle raw strings
correctly, by not skipping the 'R', opening quote, delimiter
and opening parenthesis.
For example, an attempt to underline chars 4-7 with caret at 6 of
this raw string yields this erroneous output:
__emit_string_literal_range (R"foo(
0123456789)foo",
~~^~
With the patch, the correct range/caret is printed:
__emit_string_literal_range (R"foo(
0123456789)foo",
~~^~
