rtlanal.c:5210:38: runtime error: shift exponent

runtime: fixes for -buildmode=c-archive
With -buildmode=c-archive, initsig is called before the memory
allocator has been initialized. The code was doing a memory
allocation because of the call to funcPC(sigtramp). When escape
analysis is fully implemented, that call should not allocate. For
now, finesse the issue by calling a C function to get the C function
pointer value of sigtramp.
When returning from a call from C to a Go function, a deferred
function is run to go back to syscall mode. When the call occurs on a
non-Go thread, that call sets g to nil, making it impossible to add
the _defer struct back to the pool. Just drop it and let the garbage
collector clean it up.

rs6000: Testcases for rl*i*
These testcases test that we generate the expected code for all of the
rl*i* instructions, that is, rotate-and-mask and rotate-and-mask-insert
for immediate rotation counts. All the testcases do rotate, shift left,
as well as shift right; if that results in an instruction that does not
exist the testcases generate a multiplication instead, so that we can
detect if this is handled properly.
Many 32-bit instructions zero-extend their result properly in 64-bit
mode, but the rs6000 port does not yet know. These testcases test the
status quo, so they will need updating when ever we handle this.

rs6000: Make deallocation of a large frame work (PR77687)
If we use ABI_V4 and we have a big stack frame, we end the epilogue
with a "mr 1,11" (or similar) instruction. This instruction however
has no dependencies on the earlier restores from stack (done via r11),
so sched2 can end up reordering the insns, which is bad because we
have no red zone so that you then restore from stack that is already
deallocated.
This fixes it by making that restore depend on the memory accesses.

shrink-wrap: New spread_components
This patch changes spread_components to use a simpler algorithm that
puts prologue components as early as possible, and epilogue components
as late as possible. This allows better scheduling, and also saves a
bit of code size. The blocks that run with some specific component
enabled after this patch is a strict superset of those that had it
before the patch.
It does this by finding for every component the basic blocks where that
component is not needed on some path from the entry block (it reuses
head_components to store this), and similarly the blocks where the
component is not needed on some path to the exit block (or the exit can
not be reached from that block) (stored in tail_components). Blocks
that then are not in both of those two sets get the component active.

[Darwin] fix PR67710 by updating 'as' specs to handle newer assembler versions.
A/ Newer versions of ld64 check the min_version command, and newer versions of
the system assembler inserts this in response to "-mmacosx-version-min=" on
the assembler line. Unless one makes sensible versions, some object is bound
to conflict.
B/ Additionally, there's a difference in behaviour between "as" and "ld" when
presented with xx.yy.zz (ld truncates to xx.yy, as doesn't); net result is
that one needs to pass a truncated version to "as".
So (if the assembler supports minversion commands)
(a) provide a truncated minversion (as asm_macosx_version_min, which is a
driver-only var).
(b) pass this to "as"
(c) Update tests to determine 'HAVE_AS_MMACOSX_VERSION_MIN_OPTION'
(Rainer's patch)
(d) For some reason the testcases are "run" (it's not obvious they need to be,
they are checking compile-time issues)
- anyway, to preserve the status quo, I've left them as exec. However, the
minimum version that can be code-gened for is target-dependent (there are no
released x86 versions before 10.4, for example). To avoid conflicts where
the "as" is assuming some minimum, I've set the testversion to 10.5 (which
is supported by all the archs we have)
(e) We need to ensure that libgcc and crts are generated with a sufficiently
old minversion not to conflict.

[Darwin] Fix PR57438 by avoiding empty function bodies and trailing labels.
A.
Empty function bodies causes two problems for Darwin's linker (i) zero-length
FDEs and (ii) coincident label addresses that might point to items of
differing weakness.
B.
Trailing local labels can be problematic when they end a function because
similarly they might apparently point to a following weak function, leading
to the linker concluding that there's a pointer-diff to a weak symbol
(which is not allowed).
Both conditions arise from __builtin_unreachable() lowering to a barrier.
The solution for both is to emit some finite amount of code; in the case of A
a trap is emitted, in the case of B a nop.
