tcg: Add TYPE parameter to tcg_out_mov.
Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64
to perform the move at the proper width, which may elide a REX prefix.
Introduce a TCG_TYPE_REG enumerator to represent the "native width"
of the host register, and to distinguish the usage from "pointer data"
as represented by the existing TCG_TYPE_PTR.
Update all targets to match.
