[PATCH][committed] aarch64: PR target/99195 annotate vector compare patterns for vec-concat-zero

[Kyrylo Tkachov via Gcc-patches]

Hi all,

This instalment of the series goes through the vector comparison patterns in 
the backend.
One wart are the int64x1_t comparisons that this patch doesn't touch.
Those are a bit trickier because they have define_insn_and_split mechanisms for 
falling back to
GP reg comparisons after reload and I don't think a simple annotation will 
catch those cases correctly.
Those will need more custom thinking.
As said, this patch doesn't touch those and is a decent straightforward 
improvement on its own.

Bootstrapped and tested on aarch64-none-linux-gnu and aarch64_be-none-elf.
Pushing to trunk.

Thanks,
Kyrill
