[gc-improv] Convert PA backend

[Laurynas Biveinis]

Almost as boring as the other ones, but with the PA backed the last
ggc_resize reference goes away, thus deleting its definition.
Bootstrapped and regtested under hppa2.0-unknown-linux-gnu, committed
to gc-improv.

        * ggc.h (ggc_realloc): Remove.

        * config/pa/pa.c (pa_init_machine_status): Use typed GC allocation.
        (get_deferred_plabel): Use typed GC allocation.  Replace
        ggc_realloc with GGC_RESIZEVEC.
