* mips.h: Document microMIPS DSP ASE usage.
	(MICROMIPSOP_MASK_DSPACC, MICROMIPSOP_SH_DSPACC): Update for
	microMIPS DSP ASE support.
	(MICROMIPSOP_MASK_DSPSFT, MICROMIPSOP_SH_DSPSFT): Likewise.
	(MICROMIPSOP_MASK_SA3, MICROMIPSOP_SH_SA3): Likewise.
	(MICROMIPSOP_MASK_SA4, MICROMIPSOP_SH_SA4): Likewise.
	(MICROMIPSOP_MASK_IMM8, MICROMIPSOP_SH_IMM8): Likewise.
	(MICROMIPSOP_MASK_IMM10, MICROMIPSOP_SH_IMM10): Likewise.
	(MICROMIPSOP_MASK_WRDSP, MICROMIPSOP_SH_WRDSP): Likewise.
	(MICROMIPSOP_MASK_BP, MICROMIPSOP_SH_BP): Likewise.

	gas/
	* config/tc-mips.c (macro_build) <'2'>: Handle microMIPS.
	(macro) <M_BALIGN>: Update error handling.
	(validate_micromips_insn) <'2', '3', '4', '5', '6'>: New cases.
	<'7', '8', '0', '@', '^'>: Likewise.
	(mips_ip) <'2', '3', '4', '5', '6', '7', '8'>: Handle microMIPS.
	<'9'>: Fix formatting.
	<'0', '@'>: Handle microMIPS.
	<'^'>: New case.

	gas/testsuite/
	* gas/mips/micromips@mips32-dsp.d: New.
	* gas/mips/micromips@mips32-dspr2.d: New.
	* gas/mips/mips32-dsp.d: Remove -mips32r2.
	* gas/mips/mips32-dspr2.d: Likewise.
	* gas/mips/mips.exp: (mips_create_arch): Use -mips64r2
	for micromips.  Use run_dump_test_arches to run dsp tests.

	opcodes/
	* micromips-opc.c (WR_a, RD_a, MOD_a): New macros.
	(DSP_VOLA): Likewise.
	(D32, D33): Likewise.
	(micromips_opcodes): Add DSP ASE instructions.
	* micromips-dis.c (print_insn_micromips) <'2', '3'>: New cases.
