    PowerPC64 ELFv2 trampoline match
    
    ELFv2 needs different plt call stubs to ELFv1, register usage differs
    too.  When I added these to ld I changed register usage in the ELFv1
    stubs as well, simplifying the linker code and (perhaps) future
    maintenance.  All well and good, but this means gdb needs to cope with
    more stub variants.  This patch also handles skipping over addis/addi
    setting up r2 in ELFv2 global entry code.  We want breakpoints to be
    set past this point to catch calls via the local entry point.
    
    	* ppc64-tdep.c (ppc64_plt_entry_point): Renamed from..
    	(ppc64_desc_entry_point): ..this.  Update comments here and at
    	call points.
    	(ppc64_standard_linkage1, ppc64_standard_linkage2,
    	ppc64_standard_linkage3): Update comments.
    	(ppc64_standard_linkage4, ppc64_standard_linkage5,
    	(ppc64_standard_linkage6, ppc64_standard_linkage7): New insn
    	patterns.
    	(ppc64_standard_linkage4_target): New function.
    	(ppc64_skip_trampoline_code): Skip ELFv2 patterns too.
    	* rs6000-tdep.c (skip_prologue): Skip ELFv2 r2 setup.  Correct
    	nop match.  Fix comment wrap.
