Subject: Only call TryAnnotateScopeToken when parsing C++.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ab4c91c708ca0c7d80f513af74926271e25b2f56;p=clang

Only call TryAnnotateScopeToken when parsing C++.
 - This improves -parse-noop of Carbon.h by +2%, and I believe
   compensates for the majority of the performance regression in r58913.
