aarch64: Add testcase for vectorconvert lowering [PR110473]
Vectorconvert lowering was changed to use the convert optab directly
starting in r15-1677-gc320a7efcd35ba. I had filed an aarch64 specific
issue for this specific thing and it would make sense to add an aarch64
specific testcase instead of just having a x86_64 specific ones for
this.
Pushed as obvious after testing for aarch64-linux-gnu.
