Rename member 'Size' to 'AllocatedSize' in order to provide a hint that the allocated size may be different than the requested size. Comments are added to clarify this point. Updated the InMemoryBuffer in FileOutputBuffer.cpp to track the requested buffer size. Patch by Machiel van Hooren. Thanks Machiel! https://reviews.llvm.org/D61599 llvm-svn: 361195
