crtbegin.asm (__do_jv_register_classes): Don't forget to preserve gp.

        * config/ia64/crtbegin.asm (__do_jv_register_classes): Don't
        forget to preserve gp.
        * config/ia64/crtend.asm (__do_global_ctors_au): Ditto.

        * config/ia64/crtbegin.asm (__do_jv_register_classes): Add missing
        .prologue directive.
        Use .skip instead of data8 for .bss section to make Intel
        Assembler (ias) happy.  Minor whitespace fixups.  Make "nop 0"
        explicit in the .mib bundles and remove the unnecessary stop
        bits.  Replace local labels with normal labels, to make ias
        happy.  Don't register __do_global_ctors_aux here, do it in
        crtend.asm instead.

        * config/ia64/crtend.asm [HAVE_INIT_FINI_ARRAY]: Register
        __do_global_ctors_aux in .init_array section instead of
        declaring it as a hidden global.  Replace local labels with
        ordinary labels to make ias happy.
