48dd5e7d44 Bug fix for PR1279. When isDead is propagate by copy coalescing, we keep length 
of dead def live interval at 1 to avoid multiple def's targeting the same
register. The previous patch missed a case where the source operand is live-in.
In that case, remove the whole interval.

8c3d3dce2b For PR1293: 
* Rename the FunctionType* parameter from M to FT on all the functions.
* Implement a fix for PR1293 by just asserting that library functions that
  must return pointers should have pointer typed results. This just makes
  sure that we don't attempt to use an uninitialized integer or something
  later on.

undefined values. Issue errors if there are. This gets rid of the need
for implementation or checkpoint by ensuring you can't finish a parse with
