Ahmed Bougacha ac655060b4 [ARM] Look through concat when lowering in-place shuffles (VZIP, ..) ... Currently, we canonicalize shuffles that produce a result larger than their operands with: shuffle(concat(v1, undef), concat(v2, undef)) -> shuffle(concat(v1, v2), undef) because we can access quad vectors (see PerformVECTOR_SHUFFLECombine). This is useful in the general case, but there are special cases where native shuffles produce larger results: the two-result ops. We can look through the concat when lowering them: shuffle(concat(v1, v2), undef) -> concat(VZIP(v1, v2):0, :1) This lets us generate the native shuffles instead of scalarizing to dozens of VMOVs.
