CompileFeatures: Record when compilers gained full CXX11 support
Use the infrastructure added by commit 646fb1a646 (CompileFeatures:
memoize C++ compilers with full language level support, 2019-03-27) to
avoid using a `try_compile` to check for C++11 feature support when the
running compiler is known to have all features.
