Fixed an expression parser bug that prevented
certain functions from being resolved correctly.
Some functions (particularly varargs functions)
are BitCast before being called, and the problem
was that a CallInst where getCalledValue()
returned a BitCast ConstantExpr was not being
relocated at all.
This problem should now be resolved for the case
of BitCast.
