Add clobbersPred - instruction that clobbers condition code / register which are used to predicate instructions.

llvm-svn: 37465

Add a machine instruction flag indicating the instruction can clobber condition code / register(s) used to predicate instructions.

correct machine basic block - do not rely on the eh.exception intrinsic
being in the landing pad: the loop optimizers can move it out.

- Modifications from the last patch included
  (issues pointed by Evan Cheng are now fixed).
- Added more MipsI instructions.
- Added more patterns to match branch instructions.

This is the obviously correct part of the fix for PR1487.

If a unconditional branch is added to branch to the false path during ifcvt, the predicated block cannot be iteratively ifcvted.
