[PATCH] D59745: [NFC] Move writeFuncOrVarName out of class CodegenNameGenerator so that it can be reused more easily.

[Puyan Lotfi via Phabricator via cfe-commits]

plotfi created this revision.
plotfi added reviewers: compnerd, akyrtzi.
Herald added subscribers: cfe-commits, jdoerfert, arphaman.
Herald added a project: clang.

I simply want a helper function to use for printing out mangled Decl names. I think this could be a pretty simple straightforward patch to do so, in an NFC manner.
