Subject: [PATCH] Added member template functions to MallocAllocator and
 BumpPtrAllocator that implement allocations that return a properly typed
 pointer.  For BumpPtrAllocator, the allocated memory is automatically aligned
 to the minimum alignment of the type (as calculated by
 llvm::AlignOf::Alignment).
