----------------
Why not disable MVE-I? I assume because it's integer only but then why does
-mfloat-abi=soft disable it?
If possible add a regression test for this. In general a test like the bf16
test below, but for all the listed extensions would help. Perhaps it makes more
sense to add a driver test that looks for the "-<ext>" bits in the -### output
instead of doing each extension on its own.
