    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.

The ICE in PR preprocessor/78569 appears to be due to an attempt to
generate substring locations in a .i file where the underlying .c file
has changed since the .i file was generated.

This can't work, so it seems safest for the on-demand substring
locations to be unavailable for such files, falling back to
"whole string" locations for such cases.

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.

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.

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.

Combine can turn a conditional trap into an unconditional trap.  If it
does that it should make the code after it unreachable (an unconditional
trap should be the last insn in its bb, and that bb has no successors).

This patch seems to work.  It is hard to be sure, this is very hard to
trigger.  Quite a few other passes look like they need something similar
as well, but I don't see anything else handling it yet either.
