Hey, This is my first submission of ARB_shader_subroutine, it's been through a few internal revisions in my brain, and its based on some parser work from Chris, but I may merge that stuff into mine as I change his stuff heavily.
I implemented this by extending ir_call in the end and adding a lowering pass to an if ladder. The parser changes are a bit gnarly, but I tried to stay aligned to the GLSL4.50 grammer which seems accurate for this. Also I'm open on when to enable this, I really don't care about this extension apart from the GL4.0 roadblock it has become.
