	* gas/config/tc-arm.c (thumb32_mode): Rename unified_syntax.
	All uses changed to match.
	(COND_ALWAYS): Don't offset.
	(COND_MASK): Delete.
	(struct arm_it): Add cond field.
	(struct asm_opcode): Add tag field.  Change some fields to
	unsigned int and/or to bitfields.
	(my_get_expression): If unified_syntax, always treat the
	prefix as optional.
	(s_thumb32, s_thumb32_func): Delete.
	(opcode_select, s_force_thumb): Don't set thumb32_mode.
	(s_syntax): New function.
	(md_pseudo_table): Update to match.
	(do_blx, do_iwmmxt_wldstw): Look at inst.cond, not
	inst.instruction, for the condition.
	(do_it): New function.
	(do_t_branch): Get the condition from inst.cond and patch it
	into the appropriate place.
	(output_inst): If inst.size == 0, output nothing, but do issue
	a diagnostic if any.
	(enum opcode_tag): New set of constants.
	(opcode_lookup): New function.
	(md_assemble): Use opcode_lookup.  Restructure a little.
	(conds, OPS0): Adjust comment.
	(TxCE, TxCM, TUE, TUF): Rewrite.
	(TCC): Delete.
	(TxC3, TC3, tC3, TxCM_, C3, C3E): New notational macros.

	(insns): Use TC3, tC3, or C3, as appropriate, for all
	instructions where the conditional infix appears after the
	third letter of the mnemonic.  Use TCE for 'b'.  Use C3E for
	'cmfe' and 'cnfe'.  Change 'czbne' to 'cbnz', 'czbeq' to 'cbz'.
	Use TUE, with a dummy ARM opcode, for all variants of 'it'.

	* opcodes/arm-dis.c: Change 'czbne' to 'cbnz', 'czbeq' to 'cbz'.

	* gas/testsuite/gas/arm/thumb.d: bal.n is no longer
	distinguishable from b.n.
	* gas/testsuite/gas/arm/thumb32.d: Likewise.  Change 'czbne'
	to 'cbnz', 'czbeq' to 'cbz'.
	* gas/testsuite/gas/arm/thumb32.s: Use .syntax unified.
	Change 'czbne' to 'cbnz', 'czbeq' to 'cbz'.
