Chip Davis 50dce10c5d Support the SPV_EXT_demote_to_helper_invocation extension. ... This extension provides a new operation which causes a fragment to be discarded without terminating the fragment shader invocation. The invocation for the discarded fragment becomes a helper invocation, so that derivatives will remain defined. The old `HelperInvocation` builtin becomes undefined when this occurs, so a second new instruction queries the current helper invocation status. This is only fully supported for GLSL. HLSL doesn't support the `IsHelperInvocation` operation and MSL doesn't support the `DemoteToHelperInvocation` op. Fixes #1052.		2019-07-17 09:12:22 -05:00
