We will need a backend interface for type truncation. For those backends
that did not enable TCG_TARGET_HAS_extrl_i64_i32, use tcg_out_mov.
Use it in tcg_reg_alloc_op in the meantime.

To: qemu-devel; +Cc: Philippe Mathieu-Daudé
This is common code in most qemu_{ld,st} slow paths, extending the
input value for the store helper data argument or extending the
return value from the load helper.

We will want a backend interface for register swapping.
This is only properly defined for x86; all others get a
stub version that always indicates failure.

instructions, we don't need to extend if the register matches.
This is already relied upon by comparisons.
