[COMMITTED] Use pp_vrange for ranges in dump_ssaname_info.

[Aldy Hernandez via Gcc-patches]

This changes the ad-hoc dumping of ranges in the gimple pretty printer
to use the pp_vrange utility function, which has the benefit of
handling all range types going forward and unifying the dumping code.

Instead of:
        # RANGE [0, 51] NONZERO 0x3f
        # RANGE ~[5, 10]

we would now get:

        # RANGE [irange] long unsigned int [0, 51] NONZERO 0x3f
        # RANGE [irange] int [-MIN, 4][11, MAX]

Tested on x86-64 Linux.

gcc/ChangeLog:

        * gimple-pretty-print.cc (dump_ssaname_info): Use pp_vrange.
