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. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
