It's similar to the FMNMX instruction but it works on integers.

It is unknown at this moment if we actually need to do something with these instructions or if the GLSL compiler takes care of that for us.

It's similar to the isetp and fsetp instructions but it works on predicates instead.

Like the MOV32I and FMUL32I instructions.
This fixes a potential crash when using these instructions.

This instruction tells the GPU where the flow reconverges in a non-uniform control flow scenario, we can ignore this when generating GLSL code.
