Subject: Avoid double-traversing for QualifiedTypeLoc -- we were calling
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c34c2116346a29869b47b190f6dea589823d6947;p=clang

Avoid double-traversing for QualifiedTypeLoc -- we were calling
VisitTypeLoc twice for qualified types, once for the qualified form
and once for the unqualified (though they looked the same by the time
we got to visittypeloc).  Now only visit once, which matches previous
behavior.
