[PATCH] Fix aarch64/109762: push_options/push_options does not work sometimes

[Andrew Pinski via Gcc-patches]

aarch64_isa_flags (and aarch64_asm_isa_flags) are both aarch64_feature_flags 
(uint64_t)
but since r12-8000-g14814e20161d, they are saved/restored as unsigned long. This
does not make a difference for LP64 targets but on ILP32 and LLP64IL32 targets,
it means it does not get restored correctly.
This patch changes over to use aarch64_feature_flags instead of unsigned long.

Committed as obvious after a bootstrap/test.
