[AArch64] Backport of PR target/70044 fix to GCC 5

PR target/70044
* config/aarch64/aarch64.c
(aarch64_override_options_after_change): When forcing
flag_omit_frame_pointer to be true, use a special value that can
be detected if this function is called again, thus preventing
flag_omit_leaf_frame_pointer from being forced to be false.

* gcc.target/aarch64/pr70044.c: New test.

This issue still occurs on GCC 5 though, so I think we want to keep this opened
for the backport
