[FuzzMutate] Avoid using swifterror as a source operand

When transforming arbitrary llvm ir code we may encounter swifterror operands with rather restricted semantics. In this change I simply drop such operands from possible source candidates.

I don't really like how specific of a special case this is, but I guess that's more of a problem with swifterror itself than with this pass. LGTM.
