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.

...
* 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.
