[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} git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211939 91177308-0d34-0410-b5e6-96231b3b80d8
