[PATCH][AArch64] Fix thinko in handling of -momit-leaf-frame-pointer option

[Kyrill Tkachov]

Hi all,

When extending the aarch64_handle_option function for GCC 6 I introduced a 
thinko
when handling the -momit-leaf-frame-pointer option and had it set the variable
for -fomit-frame-pointer instead. This hasn't been particularly impactful 
because
-momit-leaf-frame-pointer is on by default and will set -fomit-frame-pointer to 
true
anyway in aarch64_override_options_after_change_1, but it would be exposed by 
the fix
for PR 70044.

This patch fixes that thinko.
Bootstrapped and tested on aarch64-none-linux-gnu.

Ok for trunk?

Thanks,
Kyrill
