[PATCH, AArch64] Define __ARM_NEON by default

Authentication-results: sourceware.org; auth=none

Hi,

This is needed for when people are porting their aarch32 code to aarch64.
They will have #ifdef __ARM_NEON (as specified in ACLE) and their intrinsics
currently won't get used on aarch64 because it's not defined there by
default.

This patch defines __ARM_NEON so long as we are not using general regs only.

Tested on simple testcase to ensure __ARM_NEON was defined.

OK for trunk?

Cheers,
Ian

	not using general regs only.
