  Changed paths:
    M clang/lib/Sema/SemaDecl.cpp
    M clang/lib/Sema/SemaDeclAttr.cpp
    M clang/test/SemaCXX/ms-uuid.cpp

  Log Message:
  -----------
  Allow redeclaration of __declspec(uuid)

msvc allows a subsequent declaration of a uuid attribute on a
struct/class.  Mirror this behavior in clang-cl.
