[PATCH] ARM64: start porting regression tests from AArch64

[Ana Pazos]

Hi Tim,

I thought the initial purpose of merging the AArch64 tests to ARM64 was to increase code coverage in ARM64.

We know AArch64 has good coverage because of these regression tests.

During the meetings we had at EuroLLVM a secondary purpose came up which is to catch optimizations that might go into AArch64 and missed from being merged to ARM64.

I am ok with the modifications you made the tests.

Just want to clarify your goals.

Thanks,
Ana.

It needs both, unfortunately. llvm-lit has no way to know which RUN lines need ARM64 and which need AArch64, so it needs all of them to succeed.

Cheers.
