Subject: Fix scope location when parsing GNU attributes.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=45bed131a1a4219cc0bfb3c9f666dca54ddb59fa;p=clang

Fix scope location when parsing GNU attributes.

For GNU attributes, instead of reusing attribute source
location for the scope location, use SourceLocation() since
GNU attributes don not have scope tokens.
