* elf32-xtensa.c (splay-tree.h): include header.
(text_action_struct): drop next pointer.
(text_action_list_struct): drop head pointer, add count and
tree fields.
(find_fill_action): instead of linear search in text_action_list
search in the tree.
(text_action_compare, action_first, action_next): new functions.
(text_action_add, text_action_add_literal): instead of linear
search and insertion insert new node into the tree.
(removed_by_actions): pass additional parameter: action_list,
use it to traverse the tree.
(offset_with_removed_text): pass additional action_list parameter
to removed_by_actions.
(map_action_fn_context): new typedef.
(map_action_fn_context_struct): new structure.
(map_action_fn): new function.
(map_removal_by_action): use splay_tree_foreach to build map.
(find_insn_action): replace linear search in text_action_list
with series of splay_tree_lookups.
(print_action, print_action_list_fn): new functions.
(print_action_list): use splay_tree_foreach.
(init_xtensa_relax_info): drop action_list.head initialization.
Initialize the tree.
(compute_text_actions): use non-zero action_list_count instead of
non-NULL action list.
(xlate_map_context): new typedef.
(xlate_map_context_struct): new structure.
(xlate_map_fn): new function.
(build_xlate_map): use splay_tree_foreach to build map.
(action_remove_bytes_fn): new function.
(relax_section): use zero action_list_count instead of NULL
action list. Use splay_tree_foreach to count final section size.
Drop unused variable 'removed'.

* elf32-xtensa.c (removed_literal_map_entry): new typedef.
(removed_literal_map_entry_struct): new structure.
(removed_literal_list_struct): add new fields: n_map and map.
(map_removed_literal, removed_literal_compare): new functions.
(find_removed_literal): build index array for literals ordered
by VMA, use binary search to find removed literal.

* elf32-xtensa.c (removal_by_action_entry_struct,
removal_by_action_map_struct): new structures.
(removal_by_action_entry, removal_by_action_map): new typedefs.
(text_action_list_struct): add new field: map.
(map_removal_by_action, removed_by_actions_map,
offset_with_removed_text_map): new functions.
(relax_section): replace offset_with_removed_text with
offset_with_removed_text_map.
(translate_reloc, relax_property_section, relax_section_symbols):
replace removed_by_actions with removed_by_actions_map.

* elf32-xtensa.c (reloc_range_list, reloc_range_list_entry,
reloc_range): new typedef.
(reloc_range_list_struct, reloc_range_list_entry_struct,
reloc_range_struct): new structures.
(reloc_range_compare, build_reloc_ranges,
reloc_range_list_append, reloc_range_list_remove,
reloc_range_list_update_range, free_reloc_range_list): new
functions.
(compute_text_actions): precompute relocation opcodes before the
loop. Add relevant_relocs variable, initialize it before the
loop, pass it to the check_section_ebb_pcrels_fit.
(check_section_ebb_pcrels_fit): add new parameter:
relevant_relocs. Update address range in the relevant_relocs if
it's non-NULL and iterate only over relevant relocations.
