fc6519b457 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.

e1fed6f90d 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.

d667b5db0c 1. Make sure the use of ConstantInt::getZExtValue() for getting shift 
amount is safe.
2. Use new method on ConstantInt instead of (? :) operator.
3. Use new method uge() on ConstantInt to simplify codes.

8a51bc0379 For PR1289: 
Check at the end of the parse that there are no unresolved types and no
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
undefined things.

e35e9d07b0 Use the stat information in the Path object, if it is already obtained. This

return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.
