    X86-64: Correct CFA in _dl_runtime_resolve
    
    When stack is re-aligned in _dl_runtime_resolve, there is no need to
    adjust CFA when allocating register save area on stack.
    
    	* sysdeps/x86_64/dl-trampoline.h (_dl_runtime_resolve): Don't
    	adjust CFA when allocating register save area on re-aligned
    	stack.
