[PATCH] [AArch64] Add vcond, vcondu support.

[James Greenhalgh]

Hi,

This patch adds support for vcond and vcondu to the AArch64
backend.

Tested with no regressions on aarch64-none-elf.

OK for aarch64-branch?

(If so, someone will have to commit for me, as I do not
have commit rights.)

Thanks
James Greenhalgh
