skia2/tests/PathOpsDVectorTest.cpp
Ben Wagner ff134f20ae Compile with latest clang 7.
Changes to warnings in clang introduced by https://reviews.llvm.org/D43322
and https://reviews.llvm.org/D44883 cause warning as error failures when
building Skia. In particular this addresses return-std-move-in-c++11 and
self-assign-overloaded.
