  Changed paths:
    M clang/lib/Sema/SemaDeclObjC.cpp
    M clang/test/SemaObjC/method-direct-one-definition.m
    M clang/test/SemaObjC/method-direct.m

  Log Message:
  -----------
  [objc_direct] also go through implementations when looking for clashes

Some methods are sometimes declared in the @implementation blocks which
can cause undiagnosed clashes.

Just write a checkObjCDirectMethodClashes() for this purpose.

Also make sure that "unavailable" selectors do not inherit
objc_direct_members.
