Fraser Cormack 0176fecfbc [SVE][CodeGen] Expand SVE MULH[SU] and [SU]MUL_LOHI nodes
This patch fixes a codegen crash introduced in fde2466171, where the
DAGCombiner started generating optimized MULH[SU] or [SU]MUL_LOHI nodes
unless the target opted out. The AArch64 backend cannot currently select
any of these nodes, so ensure that they are not generated in the first
place.

This issue was raised by @huihuiz in D94501.
