[PATCH] [ARM] Fix NEON being enabled with soft-float

[Renato Golin]

  Wouldn't getARMTargetFeatures() be called for both targets? If you call clang with -target arm and no neon, would that also add -crypto to it?

  Maybe having a check on an ARM test earlier would make things clearer (like CHECK-NOT: -crypto).
