Declare __builtin_strlen in StringRef.h as constexpr
Otherwise Visual Studio 2017 will complain about
llvm::StringRef::strlen not being constexpr:
StringRef.h(80): error C3615: constexpr function 'llvm::StringRef::strLen' cannot result in a constant expression
StringRef.h(84): note: failure was caused by call of undefined function or one not declared 'constexpr'
(cherry picked from commit b3d7d1061dc375bb5ea725e6597382fcd37f41d6)
