Bevin Hansson 21be0de34d [Intrinsic] Add fixed point division intrinsics.
Summary:
This patch adds intrinsics and ISelDAG nodes for
signed and unsigned fixed-point division:

  llvm.sdiv.fix.*
  llvm.udiv.fix.*

These intrinsics perform scaled division on two
integers or vectors of integers. They are required
for the implementation of the Embedded-C fixed-point
arithmetic in Clang.
