[AArch64][ARM] Don't base interleaved op legality on type alloc size. Otherwise, we think that most types that look like they'd fit in a legal vector type are legal (so, basically, *any* vector type with a size between 33 and 128 bits, I think, since we use pow2 alignment; e.g., v2i25, v3f32, ...). DataLayout::getTypeAllocSize rounds up based on alignment. When checking for target intrinsic legality, that's not what we want: if rounding makes a difference, the type isn't legal, and the target intrinsics shouldn't be used, as they are always assumed legal. One could make the argument that alloc size is ultimately the most relevant here, since we're dealing with LD/ST intrinsics. That's only true if we did legalize them though; that's a problem for another day. Use DataLayout::getTypeSizeInBits instead of getTypeAllocSizeInBits. Type::getSizeInBits can't be used because that'd gratuitously break pointer vector support. Some of these uses are currently fine, because we only hit them when the type is already known legal (e.g., r114454). Update them for consistency. It's faster to avoid the rounding anyway! llvm-svn: 255089

[ARM, AArch64] Match additional patterns to ldN instructions When matching an interleaved load to an ldN pattern, the interleaved access pass checks that all users of the load are shuffles. If the load is used by an instruction other than a shuffle, the pass gives up and an ldN is not generated. This patch considers users of the load that are extractelement instructions. It attempts to modify the extracts to use one of the available shuffles rather than the load. After the transformation, the load is only used by shuffles and will then be matched with an ldN pattern.
