-Subject: [PATCH 3/4] xtensa: optimize find_removed_literal
-
-find_removed_literal uses linear search to find removed literal by its
-VMA. The list of literals is fixed at that point, build an ordered index
-array and use binary search instead.

-	* 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.
