This almost fell through the cracks.

Hi all,
As part of the SWITCHABLE_TARGET work I inadvertently changed the behaviour of
-mgeneral-regs-only with respect to the .arch directives that we emit.
The behaviour of -mgeneral-regs-only in GCC 5 and earlier is such that it
disallows the usage of FP/SIMD registers but does *not* stop the compiler from
emitting the +fp,+simd etc extensions in the .arch directive of the generated
assembly. This is to accommodate users who may want to write inline assembly
in a file compiled with -mgeneral-regs-only.
This patch restores the trunk behaviour in that respect to that of GCC 5 and
the documentation for the option is tweaked a bit to reflect that.
Bootstrapped and tested on aarch64.
Ok for trunk?
Thanks,
Kyrill

* config/aarch64/aarch64.c (aarch64_override_options_internal):
Do not alter target_flags due to TARGET_GENERAL_REGS_ONLY_P.
* doc/invoke.texi (AArch64 options): Mention that -mgeneral-regs-only
does not affect the assembler directives.
