This commit changes the interface of the vld[1234], vld[234]lane, and vst[1234], vst[234]lane ARM neon intrinsics and associates an address space with the pointer that these intrinsics take. This changes, e.g., <2 x i32> @llvm.arm.neon.vld1.v2i32(i8*, i32) to <2 x i32> @llvm.arm.neon.vld1.v2i32.p0i8(i8*, i32) This change ensures that address spaces are fully taken into account in the ARM target during lowering of interleaved loads and stores.
