[RFC] Allow loop vectorizer to choose vector widths that generate illegal types
Hello,
Currently the loop vectorizer will, by default, not consider vectorization
factors that would make it generate types that do not fit into the target
platform's vector registers. That is, if the widest scalar type in the
scalar loop is i64, and the platform's largest vector register is 256-bit
wide, we will not consider a VF above 4.
We have a command line option (-mllvm
