[ARM] Fix arm_neon.h with -flax-vector-conversions=none, part 3

Authored by efriedma on Oct 10 2019, 3:08 PM.



It's completely impossible to check that I've actually found all the issues, due to the use of macros in arm_neon.h, but hopefully this time it'll take more than a few hours for someone to find another issue.

I have no idea why, but apparently there's a rule that some, but not all, builtins which should take an fp16 vector actually take an int8 vector as an argument. Fix this, and add test coverage.

Thanks again! In my testing, this is enough to get the clang testsuite to pass with the default changed to -flax-vector-conversions=integer.
