32aaf89823 glsl: Rename various ir_* files to lower_* and opt_*. 
This helps distinguish between lowering passes, optimization passes, and
other compiler code.

a457ca7844 ir_dead_functions: Actually free dead functions and signatures. 
This makes linked shaders use around 36k less memory since the
built-in prototypes are now freed.

2e853ca23c glsl2: Add a pass for removing unused functions. 
For a shader involving many small functions, this avoids running
optimization across all of them after they've been inlined
post-linking.

Reduces the runtime of linking and running a fragment shader from Yo
Frankie from 1.6 seconds to 0.9 seconds (-44.9%, +/- 3.3%).
