Use rtx_mode_t instead of std::make_pair

This change makes the code less sensitive to the exact type of the mode,
i.e. it forces a conversion where necessary.  This becomes important
when wrappers like scalar_int_mode and scalar_mode can also be used
instead of machine_mode.

Using rtx_mode_t also abstracts away the representation.  The fact that
it's a std::pair rather than a custom class isn't important to users of
the interface.

Add SET_DECL_MODE

This may no longer be necessary with the current version
of the SVE patches, but it does at least make things consistent
with the TYPE_MODE/SET_TYPE_MODE split.
