Greg Fischer 48007a5c7f Add interpolate legalization pass (#4220) ... This pass converts an internal form of GLSLstd450 Interpolate ops to the externally valid form. The external form takes the lvalue of the interpolant. The internal form can do a load of the interpolant. The pass replaces the load with its pointer. The internal form is generated by glslang and possibly other frontends for HLSL shaders. The new pass is called as part of HLSL legalization after all propagation is complete. Also adds internal interpolate form to pre-legalization validation		2021-03-31 14:26:36 -04:00
