I think this code needs to use `matchesConditionally()` instead to ensure it
gets run in the correct language mode. e.g.,
```
TEST(IsExpandedFromMacro, MatchesFromCommandLine) {
StringRef input = R"cc(
void Test() { FOUR_PLUS_FOUR; }
)cc";
EXPECT_TRUE(matchesConditionally(
input, binaryOperator(isExpandedFromMacro("FOUR_PLUS_FOUR")), true,
{"-std=c++11", "-DFOUR_PLUS_FOUR=4+4"}));
}
```
but that said, these all exist in C++11 and later (though `L` was C++98), and
C11 and later (though `L` was C99), so we shouldn't need this check at all,
right?
