We were chatting about this in the patchwork sync, just writing it here in case
anyone is watching the bug.
This one isn't quite a non-functional change (even though it sort of looks like
one): before the change the default behavior is to disable the vector ABI,
after the change it's enabled by default. There's some functions with vector
arguments in here, so this patch should change the behavior.
A more interesting patch might show up bisecting with
`--param=riscv-vector-abi` enabled.
