The inline plt code emitted by gcc is incompatible with the
linker/ld.so --tls-get-addr-optimize scheme. This is the runtime
optimisation where the first call to __tls_get_addr results in
__tls_get_addr updating the tls_index pair, then the special linker
stub using that to short-circuit second and subsequent calls for a
given tls symbol. Enabled by default when the linker sees
__tls_get_addr_opt is preseent, and enabled in ld.so when DT_PPC64_OPT
has PPC64_OPT_TLS set. Note that this is distinct from link-time tls
optimisation.
PR 32387
* elf64-ppc.c (ppc64_elf_check_relocs): Disable tls_get_addr_opt
on detecting inline plt calls to __tls_get_addr.

GCC trunk now defaults to -std=gnu23. We return false in a few places
which can't work when true/false are a proper type (_Bool). Return NULL
where appropriate instead of false. All callers handle this appropriately.

static_assert is declared in C23 so we can't reuse that identifier:
* Define our own static_assert conditionally;
* Rename "static assert" hacks to _N as we do already in some places
to avoid a conflict.
ChangeLog:
PR ld/32372
* i386-gen.c (static_assert): Define conditionally.
* mips-formats.h (MAPPED_INT): Rename identifier.
(MAPPED_REG): Rename identifier.
(OPTIONAL_MAPPED_REG): Rename identifier.
* s390-opc.c (static_assert): Define conditionally.
