glsl: Verify usage of fragment interlock functions
Make the same checks as barrier(), then check for the order and uniqueness of the functions.
After this MR all the compilation tests of ARB_fragment_shader_interlock should pass.
Due to an influx of spam, we have had to impose restrictions on new accounts. Please see this wiki page for instructions on how to get full permissions. Sorry for the inconvenience.
Equinix is shutting down its operations with us on April 30, 2025. They have graciously supported us for almost 5 years, but all good things come to an end.
Given the time frame, it's going to be hard to make a smooth transition of the cluster to somewhere else (TBD). Please expect in the next months some hiccups in the service and probably at least a full week of downtime to transfer gitlab to a different place.
All help is appreciated.
