Add support to the Xtensa target for creating trampolines for out-of-range branches.
* tc-xtensa.c (xtensa_check_frag_count, xtensa_create_trampoline_frag)
(xtensa_maybe_create_trampoline_frag, init_trampoline_frag)
(find_trampoline_seg, search_trampolines, get_best_trampoline)
(check_and_update_trampolines, add_jump_to_trampoline)
(dump_trampolines): New function.
(md_parse_option): Add cases for --[no-]trampolines options.
(md_assemble, finish_vinsn, xtensa_end): Add call to
xtensa_check_frag_count.
(xg_assemble_vliw_tokens): Add call to
