--- Comment #2 from ak at gcc dot gnu.org ---
Most of it is already done as part of PR101989
One issue is that it is only for suitable vector types, it doesn't really work
for scalars because the compiler has no idea that a conversion might be
profitable. Perhaps that would be an interesting (but likely) separate feature
to define some frame work to figure out if switching to the vector ISA is worth
it.
