[Mesa-dev] Any plans to add type precision to GLSL IR (glsl_type etc.)?

Yeah, at first I thought about adding that to glsl_type, but that way
lies madness.

So I started adding it to ir_variable, ir_rvalue et al., and so far it
seems to be promising (and not hard either). Thanks for confirming
that I'm not on some crazy path!
