[PATCH][AArch64] Add __extension__ and __always_inline__ to crypto intrinsics

[Kyrill Tkachov <kyrylo dot tkachov at foss dot arm dot com>]

Hi all,

The crypto intrinsics are missing an __extension__ and an __always_inline__ attribute that all the other
intrinsics have. I don't see any reason for them to be different and the always_inline attribute will be needed
if we decide to wrap the intrinsics inside a target SIMD pragma.

Tested aarch64-none-elf.

Ok for trunk?

Thanks,
Kyrill
