With the tracing hooks, the inline functions are no longer so simple. Once out-of-line, the current tlb_entry lookup is redundant with the one in the main load/store_helper. This also begins the introduction of a new target facing interface, with suffix *_mmuidx_ra. This is not yet official because the interface is not done for user-only. Use abi_ptr instead of target_ulong in preparation for user-only; the two types are identical for softmmu. What remains in cpu_ldst_template.h are the expansions for _code, _data, and MMU_MODE<N>_SUFFIX.
