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: 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.

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.
