jit.dg: fix issue with compilation of test-threads.c

DejaGnu's <dejagnu.h> provides decls of various inline functions,
of which the jit testsuite uses "pass", "fail" and "note".

The jit testcase test-threads.c jumps through some hoops to make
these functions threadsafe, using macros to rename the implementation
in dejagnu.h, giving them a "dejagnu_" prefix, then reimplementing
the names with wrappers that use a mutex.

The DejaGnu functions gained a "static" modifier in
ad36659ffa984a0541cfc2bd27f393e0d7d173a7, which appears to be in
DejaGnu 1.5.2 onwards.

Unfortunately, jit.dg/test-threads.c has forward decls of
"dejagnu_pass" etc, and these don't have "static", leading to conflicts
with later versions of DejaGnu for which "pass" etc have "static".

This patch fixes things by removing the forward decls of
"dejagnu_pass", moving the usage of them to a point at which dejagnu.h
has been included, which ought to work with both earlier and later
versions of DejaGnu.

Fixes compilation of test-threads.c in jit testsuite.

gcc/testsuite/ChangeLog:
* jit.dg/test-threads.c (dejagnu_pass): Remove decl.
(dejagnu_fail): Likewise.

-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.
