We don't bother with replicating the fast path (tlb_hit) of the old
cpu_ldst helpers as it has no measurable effect on performance. This
probably indicates we should consider flattening the whole set of
helpers but that is out of scope for this change.

While at it, use int for both num_insns and max_insns to make

[rth: Moved max_insns adjustment from tb_start to init_disas_context.
Removed pc_next return from translate_insn.
Removed tcg_check_temp_count from generic loop.
Moved gen_io_end to exactly match gen_io_start.
Use qemu_log instead of error_report for temporary leaks.
Moved TB size/icount assignments before disas_log.]

Used later. An enum makes expected values explicit and
bounds the value space of switches.
