* config/tc-cris.c (cris_insn_first_word_frag): New.
(md_assemble): Call cris_insn_first_word_frag to get the first frag in an insn, not frag_more. Don't call dwarf2_emit_insn at end. Drop variable insn_size. (gen_bdap): Call cris_insn_first_word_frag, not frag_more. (cris_sym_leading_underscore): Wrap first as_bad parameter in _(). (cris_sym_no_leading_underscore, s_cris_file, s_cris_loc): Ditto.

32-bit branch, just set fragP->fr_subtype. Set fragP->fr_var.
<all cases>: Always set fragP->fr_var using md_cris_relax_table.
Add cases to cover all relax states.
