New Revision: 126957

URL: http://llvm.org/viewvc/llvm-project?rev=126957&view=rev
Log:
llvm::Function argument count is not a good indicator of how many arugments does the function have at source level. If we need more space, just resize vector conservatively. This vector is only used once per function.
