Bevin Hansson 4f8b0d2f56 [Intrinsic] Add fixed point saturating division intrinsics. 
Summary:
This patch adds intrinsics and ISelDAG nodes for signed
and unsigned fixed-point division:

```
llvm.sdiv.fix.sat.*
llvm.udiv.fix.sat.*
```

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