I should amend this a little.  It's unlikely that GLSL IR will go away
completely.  However, a bunch of the effort occurring to enable SPIR-V
with NIR should pave the way to perform much of the linking process
directly in NIR.  Once that happens it is possible that GLSL IR could
exist only in the front-end.  Nothing outside the GLSL compiler itself
would necessarily have to process it.  I think quite a bit of work has
to occur for that to happen.
