Reid Kleckner 9a96e42074 [ms] Allow more unqualified lookup of types in dependent base classes
Summary:
In dependent contexts where we know a type name is required, such as a
new expression, we can recover by forming a DependentNameType.

This generalizes our existing compatibility hack for default arguments
for template type parameters.

Works towards parsing atlctrlw.h, which is PR26748.

Reid Kleckner df6e4a06e4 Delay lookup of simple default template arguments under -fms-compatibility
MSVC delays parsing of default arguments until instantiation.  If the
default argument is never used, it is never parsed.  We don't model
this.

Instead, if lookup of a type name fails in a template argument context,
we form a DependentNameType, which will be looked up at instantiation
time.

This fixes errors about 'CControlWinTraits' in atlwin.h.
