glsl: don't skip GLSL IR opts on first-time compiles

Browse Source 
This basically reverts c2bc0aa7b1.

By running the opts we reduce  memory using in Team Fortress 2
from 1.5GB -> 1.3GB from start-up to game menu.

This will likely increase Deus Ex start up times as per commit
c2bc0aa7b1. However currently 32bit games like Team Fortress 2
can run out of memory on low memory systems, so that seems more
important.
