`module.map` as a module map name has been discouraged since 2014, and
Clang will soon warn on its usage. This patch renames all instances of

if users' member access doesn't specify the base name. rdar://40373279"
Previously, we saw that unconditionally omitting type names can lead to

the new member name is identical to the old one.
Post-commit review follow-up:

We already had this functionality in the FixitApplyDiagnosticConsumer,
but we also need it in the AST passes because different entries in the
API diff data may drive identical fix-its, namely a general type rename,
which can occur anywhere a DeclRef appears, but also for function overrides'
parameter type changes, which are context specific.
