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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35508 91177308-0d34-0410-b5e6-96231b3b80d8
