Options

crti.asm: Clean up trailing whitespace. 

        * config/ia64/crti.asm: Clean up trailing whitespace.
        Remove trailing hashes (#) from identifiers.

        * config/ia64/crtn.asm: Ditto.

        * config/ia64/crtend.asm: Remove trailing hashes (#) from
        identifiers.
        (__do_global_ctors_aux): Align to 32-byte boundary.  Add unwind
        directives.  Drop explicit bundling---it just makes the code
        harder to read.  Don't save/restore gp needlessly.

        * config/ia64/crtbegin.asm: Remove trailing hashes (#) from
        identifiers (they're only needed if the identifier would clash
        with a register name otherwise).
        (__do_global_dtors_aux): Align to 32-byte boundary. Add unwind
        directives.  Drop explicit bundling---it just makes the code
        harder to read.
        (__do_jv_register_classes): Ditto.
        (.fini_array): Remove "progbits" (newer
        assemblers don't like wrong section-types).
        (.init_array): Ditto.
