[PATCH] [AArch64] Remove NEON from "generic" CPU target

[Ana Pazos]

Hi tim and Artyom,

FYI we have been running several benchmarks (e.g., EEMBC, Spec2000,
Spec2006, etc.) with slp-vectorizer and neon features enabled.

It is looking  good.

We had to fix a couple of issues, we are upstreaming the fixes, some of them
overlap with the fixes ARM Ltd. has upstreamed as a result of running
Emperor test.

When ARM is done with running Emperor test, I think it will be a good time
to turn Neon feature on by default. 

Maybe Kristof can comment when that effort will be complete.

Thanks,
Ana.

Could be. I think the assembly support has been finished for a while.
If the vectorizer is active (not sure if it needs target stubs
implementing) it'd be a very good idea to try running the test-suite or
something though.

Cheers.

Tim.
