* elf32-xtensa.c (build_reloc_opcodes): New.

Browse Source 
(compute_text_actions): Use it to decode opcodes outside inner loop.
	(check_section_ebb_pcrels_fit): Add "reloc_opcodes" argument, and if
	it is set, use it to get the opcodes for relocations.
	(move_shared_literal): Adjust call to check_section_ebb_pcrels_fit.
