[AArch64] Map standard pattern names to NEON intrinsics directly.

[James Greenhalgh]

Hi,

This patch removes the need to have a standard pattern and an
aarch64_simd_blah copy of the same RTL instruction by mapping
intrinsics directly to standard pattern names.

This allows us to clean up some redundant patterns.

Regression tested on aarch64-none-elf and aarch64-none-linux-gnu
with no regressions.

OK?

Thanks,
James Greenhalgh
