[llvm-commits] [PATCH] Add malloc call utility functions

[Victor Hernandez]

Here is an update to this patch to incorporate suggested changes.

I also went ahead and started modifying the optimization passes and  
transforms to use the MallocHelper functions, so that I know I have  
the right helper functions.  The changes to the passes are not in this  
patch, but will be coming next.

Also I have included the LLParser, BitCodeReader, and VMCore changes  
that use the new malloc codegen instead of MallocInst.  Those changes  
are disabled by default until the changes to the passes are in.
