Description

Revert r369626 "[ARM] Fix lsrl with a 128/256 bit shift amount or a shift of 32"

It broke the bots, see e.g. http://lab.llvm.org:8011/builders/clang-cuda-build/builds/36275/

This patch fixes shifts by a 128/256 bit shift amount. It also fixes
codegen for shifts of 32 by delegating to LLVM's default optimisation
instead of emitting a long shift.

Tests that used to generate long shifts of 32 are updated to check for the
more optimised codegen.
