d2d7a273c5 glsl: Add comments to lower_jumps (from the commit message). 
This is essentially Luca's commit message, but placed at the top of the
file.

1802cb9baf glsl: Remove "discard" support from lower_jumps. 
The new lower_discard and opt_discard_simplification passes should
handle all the necessary transformations, so lower_jumps doesn't need to
support it.

Also, lower_jumps incorrectly handled conditional discards - it would
unconditionally truncate all code after the discard.  Rather than fixing
the bug, simply remove the code.

NOTE: This is a candidate for the 7.9 branch.

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