Subject: Add QualType case to operator< for DynTypedNode.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7685be770f653044212184f0c6e993f466ea914c;p=clang

Add QualType case to operator< for DynTypedNode.

This allows sorting DynTypedNode's which are QualType's since QualType does
not have memoization.
