lima/gpir/sched: Handle more special ops in can_use_complex()

We were missing handling for a few other ops that rearrange their
sources somehow in codegen, namely complex2 and select.

This should fix spec@glsl-1.10@execution@built-in-functions@vs-asin-vec3
and possibly other random regressions from the new scheduler which were
supposed to be fixed in the commit right after.
