Amongst other changes, r266077 updated value_range_base::dump so
that it additionally prints the type. This broke an assertion within
the jit testsuite, in jit.dg/test-sum-of-squares.c, which was checking
for:
": [-INF, n_"
but was now getting:
": signed int [-INF, n_"
The test is merely intended as a simple verification that we can read
dump files via gcc_jit_context_enable_dump.
This patch loosens the requirements on the dump so that it should work
with either version of value_range_base::dump.

This patch started off just by adding if_then_else support in
write_attr_value to be able to write a saner expression for powerpc
tls_gdld_nomark length. Then I noticed bit-rot in functions used to
calculate insn_default_length, insn_min_length, and length_unit_log
(which are used by the shorten_branches pass). These functions
don't handle a const_int length value and return an "unknown" status
that isn't used, or in the case of or_attr_value, doesn't need to be
used. min_attr_value also attempts to return INT_MAX for the
unhandled rtl case, but this can get lost in recursive calls. I fixed
that problem by returning INT_MIN instead, and translating that to
INT_MAX in the only caller of min_attr_value.

PR c/88726).
Bugs 88720 and 88726 report issues where a function is declared inline
in an inner scope, resulting in spurious diagnostics about it being
declared but never defined when that scope is left (possibly in some
cases also wrongly referring to the function as a nested function).
These are regressions that were introduced with the support for C99
inline semantics in 4.3 (they don't appear with 4.2; it's possible
some aspects of the bugs might have been introduced later than 4.3).
For the case of functions being wrongly referred to as nested,
DECL_EXTERNAL was not the right condition for a function being
non-nested; TREE_PUBLIC is appropriate for the case of non-nested
functions with external linkage, while !b->nested means this is the
outermost scope in which the function was declared and so avoids
catching the case of a file-scope static being redeclared inline
inside a function.
For the non-nested, external-linkage case, the code attempts to avoid
duplicate diagnostics by diagnosing only when scope != external_scope,
but actually scope == external_scope is more appropriate, as it's only
when the file and external scopes are popped that the code can
actually tell whether a function ended up being defined, and all such
functions will appear in the (GCC-internal) external scope.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

This is following CL 156038. doscanstackswitch uses the same
mechanism of switching goroutines as getTraceback, and so has
the same problem as described in issue golang/go#29448. This CL
applies the same fix.

This is the gccgo version of https://golang.org/cl/141822:
Only return a pointer p to the new slices backing array from makeslice.
Makeslice callers then construct sliceheader{p, len, cap} explictly
instead of makeslice returning the slice.
This change caused the GCC backend to break the runtime/pprof test by
merging together the identical functions allocateReflectTransient and
allocateTransient2M. This caused the traceback to be other than
expected. Fix that by making the functions not identical.
This is a step toward updating libgo to the Go1.12beta1 release.

Currently, when collecting a traceback for another goroutine,
getTraceback calls gogo(gp) switching to gp, which will resume in
mcall, which will call gtraceback, which will set up gp->m. There
is a gap between setting the current running g to gp and setting
gp->m. If a profiling signal arrives in between, sigtramp will
see a non-nil gp with a nil m, and will seg fault. Fix this by
setting up gp->m first.
Fixes golang/go#29448.

offsets to maintain pointer disambiguation info. This patch makes sure
that we don't try to do the same optimisation for IFN_MASK_STOREs, which

The use of "j" in:
init = permute_results[number_of_vectors - j - 1];
was out-of-sync with the new flat loop structure. Now that all that
reversing is gone, we can just use the result of duplicate_and_interleave
directly.
The other cases shouldn't be affected by postponing the insertion
of ctor_seq, since gimple_build* appends to the seq without clearing
it first (unlike some of the gimplify routines).
The ICE is already covered by gcc.dg/vect/pr63379.c.

Investigating PR target/86891 revealed a number of issues with the way
the AArch64 backend was handing overflow detection patterns. Firstly,
expansion for signed and unsigned types is not the same as in one form
the overflow is detected via the C flag and in the other it is done
via the V flag in the PSR. Secondly, particular care has to be taken
when describing overflow of signed types: the comparison has to be
performed conceptually on a value that cannot overflow and compared to
a value that might have overflowed.
It became apparent that some of the patterns were simply unmatchable
(they collapse to NEG in the RTL rather than subtracting from zero)
and a number of patterns were overly restrictive in terms of the
immediate constants that they supported. I've tried to address all of
these issues as well.

When compiling an empty loop:

#pragma acc parallel num_gangs (640) num_workers(1) vector_length (128)
#pragma acc loop
for (v1 = 0; v1 < 20; v1 += 2)

...
the compiler emits two subsequent bar.syncs. This triggers some bug on my
quadro m1200 (I'm assuming in the ptxas/JIT compiler) that hangs the testcase.
This patch works around the bug by doing an optimization: we detect that this is
an empty loop (a forked immediately followed by a joining), and don't emit the
barriers.
The patch does not include the test-case yet, since vector_length (128) is not
