BSF_GNU_INDIRECT_FUNCTION.
* eval.c (evaluate_subexp_standard): Support TYPE_GNU_IFUNC.
* gdbtypes.c (init_type): Support TYPE_FLAG_GNU_IFUNC,
builtin_func_func, nodebug_text_gnu_ifunc_symbol and
nodebug_got_plt_symbol.
* gdbtypes.h (enum type_flag_value): New entry TYPE_FLAG_GNU_IFUNC.
(TYPE_GNU_IFUNC): New.

(in_gnu_ifunc_stub): New.
(prim_record_minimal_symbol, find_solib_trampoline_target): Support
mst_text_gnu_ifunc.
* parse.c (write_exp_msymbol): New variable ifunc_msym. Detect and
support mst_text_gnu_ifunc. Support mst_slot_got_plt.
* solib-svr4.c (svr4_in_dynsym_resolve_code): Return true also for
in_gnu_ifunc_stub.
* symmisc.c (dump_msymbols): Support mst_text_gnu_ifunc.
