If the inlined function defines a min legal vector width, then ensure the calling function has the same or larger min legal vector width.
If the caller has the attribute, but the callee doesn't, we need to remove the attribute from the caller since we can't make any guarantees about the caller's requirements. This function is called after the inlining decision has been made so we have to merge the attribute this way. Heuristics that would use min-legal-vector-width to determine inline compatibility would need to be handled as part of inline cost analysis.
