Tim Northover 1f70cb9c14 AArch64: skip select/setcc combine in complex case.
In an llvm-stress generated test, we were trying to create a v0iN type and
asserting when that failed. This case could probably be handled by the
function, but not without added complexity and the situation it arises in is
sufficiently odd that there's probably no benefit anyway.

Should fix PR20775.
