Chip Davis 2219c4a392 MSL: Support SPV_EXT_demote_to_helper_invocation for MSL 2.3. ... MSL 2.3 has everything needed to support this extension on all platforms. The existing `discard_fragment()` function was given demote semantics, similar to Direct3D, and the `simd_is_helper_thread()` function was finally added to iOS. I've left the old test alone. Should I remove it in favor of these?		2020-10-13 00:25:32 -05:00
