This implements PPCTargetLowering::getTgtMemIntrinsic for Altivec load/store intrinsics. As with the construction of the MachineMemOperands for the intrinsic calls used for unaligned load/store lowering, the only slight complication is that we need to represent a larger memory range than the loaded/stored value-type size (because the address is rounded down to an aligned address, and we need to conservatively represent the entire possible range of the actual access). This required adding an extra size field to TargetLowering::IntrinsicInfo, and this was done in a way that required no modifications to other targets (the size defaults to the store size of the provided memory data type). This fixes test/CodeGen/PowerPC/unal-altivec-wint.ll (so it can be un-XFAILed). llvm-svn: 215512
