* elf32-xtensa.c (analyze_relocations): Zero src_count if not relaxing. 

(find_relaxable_sections): Do not increment src_count for unknown
	opcodes.  Decode only once instead of calling is_l32r_relocation.
	(compute_text_actions): Remove unused no_insn_move flag.  Assert that
	src_next matches src_count in relax_info.
