Re: [cxx-abi-dev] Mangling late-specified return types/decltype

[Jason Merrill <jason@xxxxxxxxxx>]

The conversion mangling I added in that patch breaks binary 
compatibility with existing code; I didn't realize that conversions were 
already being mangled in some cases.  So let's just drop it for now, as 
the type stub manglings cover uses with decltype.

  Add manglings for type stub expressions, call expressions, char*_t, and
  N-argument functional casts.  Change argument pack mangling.
