[NVPTX] Fix handling of ldg/ldu intrinsics. The address space of the pointer must be global (1) for these intrinsics. There must also be alignment metadata attached to the intrinsic calls, e.g. %val = tail call i32 @llvm.nvvm.ldu.i.global.i32.p1i32(i32 addrspace(1)* %ptr), !align !0 !0 = metadata !{i32 4} llvm-svn: 211939

[NVPTX] Make the alignment an explicit argument to ldu/ldg Summary: Instead of specifying the alignment as metadata which may be destroyed by transformation passes, make the alignment the second argument to ldu/ldg intrinsic calls.
