gcc-4.9 on Debian 8 doesn't support multi-line constexpr functions.

CONSTEXPR_MULTILINE enables constexpr for MSVC 2022 and gcc-5,
and later versions.

CONSTEXPR_MULTILINE_NO_MSVC enables constexpr for gcc-5 and later,
but not MSVC. Needed for functions that use intrinsics, which
(still) aren't marked as constexpr on MSVC.
