[AArch64/AArch64-4.7] Fix warning - aarch64_simd_make_constant has no prototype.

[James Greenhalgh]

Hi,

aarch64_simd_make_constant has no prototype, but it doesn't
need one as it should be declared static.

This patch fixes the warning:

config/aarch64/aarch64.c:6574:1: warning: no previous prototype for 
‘aarch64_simd_make_constant’ [-Wmissing-prototypes]

Which is hidden when building with g++, but looks like:

config/aarch64/aarch64.c:6590:1: warning: no previous declaration for 
‘aarch64_simd_make_constant’ [-Wmissing-declarations]

On Trunk.

Regression tested with no regressions on aarch64-none-elf.

OK for trunk and aarch64-4.7-branch?

Thanks,
James Greenhalgh
