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.
