LGTM; one trivial comment added to codereview.
I also have some suggestions for diagnostic wording, but they're unrelated
to the patch itself:
def warn_attribute_argument_not_lockable : Warning< "%0 attribute requires
arguments whose type is annotated " "with 'lockable' attribute">,
It would be useful for this diagnostic to point at the problematic argument
and mention its type: "'guarded_by' attribute argument type 'MyMutex' is
not annotated with 'lockable' attribute"
def warn_attribute_argument_not_class : Warning< "%0 attribute requires
arguments that are class type or point to class type">, InGroup<ThreadSafety>,
This would read more naturally as "requires arguments that are of class
type or pointer to class type". It would be useful to include the type here
