intel/compiler: move nir_lower_bool_to_int32 before nir_lower_locals_to_regs

The former expects to see SSA-only things, but the latter injects registers.

The assertions in the lowering where not seeing this because they asserted
on the bit_size values only, not on the is_ssa field, so add that assertion
too.
