This moves the code that handles stripping debug info intrinsic from StripDebugInfo(Module) to StripDebugInfo(Function). The latter is already walking every instructions so it makes sense to do it at the same time. This makes also stripDebugInfo(Function) as an API more useful: it is really dropping every debug info in the Function. Finally the existing code is trigerring an assertion when the Module is not fully materialized. From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 268847
