pa.c (hppa_legitimize_address): Handle full offsets for PA2.0 FP loads and stores. 

* pa.c (hppa_legitimize_address): Handle full offsets for PA2.0
        FP loads and stores.
        (following_call): Always return zero for the PA8000.
        * pa.h (GO_IF_LEGITIMATE_ADDRESS): Handle full offsets for PA2.0
        FP loads and stores.
        (LEGITIMIZE_RELOAD_ADDRESS): Similarly.
