patch for tentative early DMI parsing

This patch series (for GCC 13) adds a mode that tries to parse nested class=
 DMI
at the end of the nested class rather than at the end of all enclosing clas=
ses.
 If that fails, we try again at the later point.

The first patch in the series extends our existing name-clash checking to c=
over
nested classes as well, to catch the case where this can change name lookup
results.=
