In order to import patterns for these, we need to define new ops that can map to the AArch64ISD::[SU]ITOF nodes. We then transform fpr->fpr variants of the generic opcodes to these custom opcodes in preisel-lowering. We have to do it here and not the PostLegalizer combiner because this has to run after regbankselect.
