This does add some extra superfluous whitespace (eg: "int *") intended to make the Simplified Template Names work easier - this makes the DIE-based names match more exactly the clang-generated names, so it's easier to identify cases that don't generate matching names. (arguably we could change clang to skip that whitespace or add some fuzzy matching to accommodate differences in certain whitespace - but this seemed easier and fairly low-impact)
