Ok, sure.

FWIW, the prime motivation behind all this, is to make sure that these 
testcases still compile successfully in this form, when downstream applies 
patches like 
https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/blob/19/debian/patches/clang-arm-default-vfp3-on-armv7a.patch?ref_type=heads.

Previously, testing that was a bit hard as we didn't pass the `-target-feature` 
flags when calling `-cc1as`, but as we do now, we can definitely test that (and 
the actual `RUN` when we try to assemble things, which isn't really kosher in 
`clang/test/Driver`, perhaps even could be skipped - although it's nice to have 
for extra test coverage).
