lgtm with the test fix.

Comment at: clang/unittests/Frontend/CompilerInvocationTest.cpp:267
- ASSERT_THAT(GeneratedArgs, Contains(StrEq("-fdebug-pass-manager")));
+ ASSERT_EQ(count(GeneratedArgs, "-fdebug-pass-manager"), 1);
ASSERT_THAT(GeneratedArgs, Not(Contains(StrEq("-fno-debug-pass-manager"))));
