4f73706838 ifcvt a triangle: don't merge ifcvt block with rejoin block if it can fall through to it. If merged, the resulting block is not a candidate for iterative ifcvting since it contains both predicated and non-predicated code.

Evan, please check that this is in fact correct.

2897eb89d0 Optimize this test. Firstly, only Instructions may use other Instructions. 
Secondly, checking whether removal succeeded tells you whether it was in
the map to begin with.

484bdb927b Additional fix for PR1422: make sure the landing pad label is placed in the 
correct machine basic block - do not rely on the eh.exception intrinsic
being in the landing pad: the loop optimizers can move it out.

  (issues pointed by Evan Cheng are now fixed).
- Added more MipsI instructions.
- Added more patterns to match branch instructions.
