ir3/ra: Handle huge merge sets

It can happen that we create an enormous merge set, even larger than the
entire register file, in which case find_best_gap() would loop
infinitely. This seems to be triggered more often with
IR3_SHADER_DEBUG=spillall, since it actually happened with a CTS test.
Just bail out in that case.

Fixes: 0ffcb19b9d9 ("ir3: Rewrite register allocation")
