wide-int, darwin

[Mike Stump]

Richi has asked the we break the wide-int patch so that the individual port and 
front end maintainers can review their parts without have to go through the 
entire patch.    This patch covers the darwin port.

Ok?


        * config/darwin.c
        (darwin_mergeable_constant_section): Use wide-int interfaces.
        (machopic_select_rtx_section): Update to handle CONST_WIDE_INT.
