[PATCH] D120129: [NVPTX] Enhance vectorization of ld.param & st.param

[Johannes Doerfert via Phabricator via cfe-commits]

This revision now requires changes to proceed.

Please revert this commit. It breaks any code using the cuda.11.0.2 libdevice.bc file, the source of the `null` `nvvm.annotations` and the annotations with 5 arguments. See below.
Once a fix is in, and a test is added, we can reapply this.

  $ opt -S .../cuda-11.0.2/nvvm/libdevice/libdevice.10.bc | tail
  !nvvm.annotations = !{!1, !2, !1, !3, !3, !3, !3, !4, !4, !3}
