glsl: Remove ir_binop_greater and ir_binop_lequal expressions
NIR does not have these instructions. TGSI and Mesa IR both implement
them using < and >=, repsectively. Removing them deletes a bunch of
code and means I don't have to add code to the SPIR-V generator for
them.
v2: Rebase on 2+ years of change... and fix a major bug added in the
rebase.
