[cfe-dev] Late-parsing function templates in tools

[Reid Kleckner via cfe-dev]

No, it doesn't do that, but it's right where we'd go through and parse all
the late-parsed templates for tools.

Honestly, I think delayed template parsing may be nearing the end of its
useful life. It may be causing more problems than it solves for users. We
should re-examine what MSVC allows in its default build modes and see if we
can get it turned off by default. Most Windows system headers these days
are supposed to be compilable with /permissive-, which is more conforming.
