[cfe-commits] [PATCH] Thread-safety analysis: properly handle attributes on functions with separate definitions.

[Delesley Hutchins]

This patch fixes thread safety attributes so that attributes which are
applied to a function declaration will be properly rewritten when
transferred to the definition.  E.g.

class Foo {
  void foo(MyObj *o) EXCLUSIVE_LOCKS_REQUIRED(o->mu_);
}

// o->mu_ must be rewritten to obj->mu_ in this scope.
Foo::foo(MyObj *obj)  { ... }

We do this by storing the original Decl that the attribute was
attached to.  When examining the attribute later, if the original Decl
does not match the current Decl, it is rewritten to the current Decl.
