-mstack-protector-guard and friends (PR78875)

Currently, on PowerPC, code compiled with -fstack-protector will load
the canary from -0x7010(13) (for -m64) or from -0x7008(2) (for -m32)
if GCC was compiled against GNU libc 2.4 or newer or some other libc
that supports -fstack-protector, and from the global variable
__stack_chk_guard otherwise.

This does not work well for Linux and other OS kernels and similar.
For such non-standard applications, this patch creates a few new
command-line options.  The relevant new use cases are:

-mstack-protector-guard=global
Use the __stack_chk_guard variable, no matter how this GCC was
configured.

-mstack-protector-guard=tls
Use the canary from TLS.  This will error out if this GCC was built
with a C library that does not support it.

-mstack-protector-guard=tls -mstack-protector-register=<reg>
-mstack-protector-offset=<offset>
Load the canary from offset <off> from base register <reg>.

This patch simplifies the handling of EH return.

This patch simplifies the handling of EH return.  We force the use of the
frame pointer so the return location is always at FP + 8.  This means we
can emit a simple volatile access in EH_RETURN_HANDLER_RTX without needing md
patterns, splitters and frame offset calculations.  The new implementation also
fixes various bugs in aarch64_final_eh_return_addr, which does not work with
-fomit-frame-pointer, alloca or outgoing arguments.

Make rtl_split_edge work for jumps that fall through (PR72749)

If a jump always falls through but that cannot be optimised away, like
is the case with the PowerPC bdnz insn if its jump target is the same as
the fallthrough, sched gets confused if it schedules some instructions
from before that jump instruction to behind it: it splits the
fallthrough branch, but the jump target isn't updated, and things fall
apart as in the PR.  This patch fixes it.

The second patch fragment makes -fsched-verbose=N work for N>=4; the

seems to work fine with that.
