(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.
