New Revision: 141702

URL: http://llvm.org/viewvc/llvm-project?rev=141702&view=rev
Log:
Support/DataTypes.h: Clean up some types and add matching (but presumably
unused) code from .cmake to DataTypes.h.in so that the files are essentially in
sync module differences in autoconf/cmake replacement syntax.
