  -----------
  Actually, don't try to use __builtin_strlen in StringRef.h before VS 2019

The fix in b3d7d1061dc375bb5ea725e6597382fcd37f41d6 compiled nicely,
but didn't link because at least the VS 2017 version I use doesn't
have the builtin yet. Instead, make use of the builtin with MSVC
conditional on VS 2019 or later.
