[PATCH] [AArch64] Change int64_t from 'long long int' to 'long int' for AArch64 target.

Hi Ana,

That would change int64_t to "long long" on AArch64 Linux wouldn't it?
I think it's entirely intentional that int64_t is long (it is on other
64-bit platforms). We've probably just got to cope with the platform
differences in our arm_neon.h and clang.

Cheers.
