teak-llvm/llvm/lib/Demangle/MicrosoftDemangleNodes.cpp
Zachary Turner 38d2edd60d [MS Demangler] Add output flags to all function calls. 
Previously we had a FunctionSigFlags, but it's more flexible
to just have one set of output flags that apply to the entire
process and just pipe the entire set of flags through the
output process.

This will be useful when we start allowing the user to customize
the outputting behavior.
