* tm-hppa.h (NUM_REGS): Bump to 128 registers.

Browse Source 
(REGISTER_NAMES): Add entries for "right-half" of FP registers.
        (REGISTER_RAW_SIZE, MAX_REGISTER_RAW_SIZE): Do not treat FP regs
        differently.  All registers are four bytes.
        (REGISTER_BYTES, REGISTER_BYTE): Simplify now that all registers are
        the same size.
        (REGISTER_VIRTUAL_TYPE): Use builtin_type_float for all FP regs.

        * hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
        registers as both single and double values (fetching 2nd 32bit half
        as necessary).  Annotate each register printed with its precision.
