Hi,

This straightforward patch fixes the following warnings I see when building
for AArch64.

gcc/config/aarch64/aarch64.c:6385:7: warning: unused variable ‘reg’ [-Wunused-variable]
gcc/config/aarch64/aarch64.c:6385:12: warning: unused variable ‘mem’ [-Wunused-variable]
gcc/config/aarch64/aarch64.c:6385:17: warning: unused variable ‘addr’ [-Wunused-variable]
gcc/config/aarch64/aarch64.c:6386:7: warning: unused variable ‘load’ [-Wunused-variable]
gcc/config/aarch64/aarch64.c:6669:17: warning: variable ‘mod_s’ set but not used [-Wunused-but-set-variable]

Regression tested on aarch64-none-elf with no regressions and checked
to ensure that the warnings go away.

OK to commit?

Thanks,
James Greenhalgh
