commit 6a8939044781191d685e0aaeb78fe34a97ee3d55

    Add _bfd_elf_ifunc_get_synthetic_symtab
    
    In i386 and x86-64 binaries with ifunc, relocations against .got.plt
    section may not be in the same order as entries in PLT section.  This
    patch adds _bfd_elf_ifunc_get_synthetic_symtab.  It takes a function
    pointer which returns an array of PLT entry symbol values.  It calls
    the function pointer to get the PLT entry symbol value array indexed
    by relocation index, instead of calling plt_sym_val on each relocation
    index.
