wide-int, vax

[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 vax port.

Ok?


        * config/vax/vax.c: Include wide-int.h.
        (vax_float_literal): Use real_from_integer.
