When "delayed parsing" C++ default arguments, if there is an error, there may be tokens left in the token stream
that will interfere (they will be parsed as if they are after the class' '}') and a crash will occur because
the CachedTokens that holds them will be deleted while the lexer is still using them.

Make sure that the tokens of default args are removed from the token stream.
Fixes PR6647.

the underlying/instantiated decl) through a lot of API, including "intermediate"
MemberExprs required for (e.g.) template instantiation.  This is necessary
because of the access semantics of member accesses to using declarations:
only the base class *containing the using decl* need be accessible from the
naming class.

This allows us to complete an access-controlled selfhost, if there are no
recent regressions.

dyn_cast) invocations for C++ and Objective-C types, declarations,
expressions, and statements. The statistics will be printed when
-print-stats is provided to Clang -cc1, with results such as:

277073 clang - Number of checks for C++ declaration nodes
 13311 clang - Number of checks for C++ expression nodes
    18 clang - Number of checks for C++ statement nodes
174182 clang - Number of checks for C++ type nodes
 92300 clang - Number of checks for Objective-C declaration nodes
  9800 clang - Number of checks for Objective-C expression nodes
     7 clang - Number of checks for Objective-C statement nodes
 65733 clang - Number of checks for Objective-C type nodes

The statistics are only gathered when NDEBUG is not defined, since
they introduce potentially-expensive operations into very low-level
routines (isa).
