nir/loop_analyze: Use try_eval_const_alu and induction variable basis info

This dramatically simplifies will_break_on_first_iteration, and, much
more importantly, makes it significantly more flexible. It is now
possible to handle loops with more complex exit condition and other
kinds of increment operations.
