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.

and expression separately.  We can get around this, however, by only keeping
opaque values in TMP_GEN.

VMCore, BitCode, and Assembly. Documentation and test case paramattrs.ll
updated also.

If the predicated block requires an early exit, end the block there and add a unconditional branch to false block. AnalyzeBranch() does not understand early exits.
