    Support fusion for ELFv2 stubs
    
    Power8 fuses addis,addi and addis,ld sequences when the target of the
    addis is the same as the addi/ld.  Thus
        addis r12,r2,xxx@ha
        addi r12,r12,xxx@l / ld r12,xxx@l(r12)
    is faster than
        addis r11,r2,xxx@ha
        addi r12,r11,xxx@l / ld r12,xxx@l(r11)
    So use the form that allows fusion in plt call and branch stubs.
    
    bfd/
    	* elf64-ppc.c (ADDIS_R12_R2): Define.
    	(build_plt_stub): Support fusion on ELFv2 stub.
    	(ppc_build_one_stub): Likewise for plt branch stubs.
    gold/
    	* powerpc.cc (addis_12_2): Define.
    	(Stub_table::do_write): Support fusion on ELFv2 stubs.
    ld/testsuite/
    	* ld-powerpc/elfv2exe.d: Update for changed plt call stubs.
