* config/tc-xtensa.c (xtensa_j_opcode): New.
(xg_instruction_matches_option_term): Handle "FREEREG" option.
(xg_build_to_insn): Likewise. Update renamed tls_reloc reference.
(md_begin): Initialize xtensa_j_opcode.
(md_assemble): Update renamed tls_reloc reference. Handle "j.l".
(xg_assemble_vliw_tokens): Save free_reg info in the frag.
(tinsn_immed_from_frag): Get free_reg info back out of the frag.
(vinsn_to_insnbuf): Update renamed tls_reloc references.
Distinguish extra argument for "FREEREG" from extra TLS argument.
* config/tc-xtensa.h (struct xtensa_frag_type): Add free_reg field.
* config/xtensa-istack.h (struct tinsn_struct): Rename tls_reloc
field to extra_arg.
* config/xtensa-relax.c (widen_spec_list): Add rules to relax "j.l".
