I think it's because we haven't done the work to make c++14 in the expression evaluator work, but the default clang language is c++14. So we downgrade it silently to c++11 here.

We should really fix that, but I think this broke some tests in the past when we tried enabling it (see `8cb75745412e4bc9592d2409cc6cfa4a2940d9e7`, https://reviews.llvm.org/D80308)
