  Log Message:
  -----------
  [Intrinsic] Add sshl.sat/ushl.sat, saturated shift intrinsics.

Summary:
This patch adds two intrinsics, llvm.sshl.sat and llvm.ushl.sat,
which perform signed and unsigned saturating left shift,
respectively.

These are useful for implementing the Embedded-C fixed point
support in Clang, originally discussed in
http://lists.llvm.org/pipermail/llvm-dev/2018-August/125433.html
and
