teemperor created this revision.
This test was silently failing since a long time because it failed to include
stdlib.h (as it's running in a freestanding environment). However, because we
used just `not clang_cc1` instead of the verify mode, this regression was never
noticed and the test was just always passing.
This adds -ffreestanding to the invocation, so that tmmintrin.h doesn't
indirectly include mm_malloc.h, which in turns includes the unavailable
stdlib.h. We also run now in the -verify mode to prevent that we silently
regress again.
I've also updated the test to no longer check the return value of
`_mm_alignr_epi8` as this is also causing it to fail (and it's not really the
job of this test to test this).
