* doc/extend.texi (MIPS DSP Built-in Functions): Document the DSP

REV 2.
* doc/invoke.texi (-mdspr2): Document new option.
* config/mips/mips.md (UNSPEC_ABSQ_S_QB .. UNSPEC_DPSQX_SA_W_PH):
New unspec for DSP REV 2.
(<u>mulsidi3_32bit_internal): Check if !TARGET_DSPR2, because
these instructions are extended in DSP REV 2.
(mips-dspr2.md): Include.
* config/mips/mips.opt (mdspr2): New option.
* config/mips/mips.c (mips_function_type): Add MIPS_V4QI_FTYPE_V4QI,
MIPS_SI_FTYPE_SI_SI_SI, MIPS_DI_FTYPE_DI_USI_USI, MIPS_DI_FTYPE_SI_SI,
MIPS_DI_FTYPE_USI_USI, MIPS_V2HI_FTYPE_SI_SI_SI.
(override_options): Check TARGET_DSPR2 to enable MASK_DSP.
(CODE_FOR_mips_mul_ph): Define it to CODE_FOR_mulv2hi3.
(dsp_bdesc): Add DSP REV 2 builtins.  Remove 32-bit only DSP builtins.
(dsp_32only_bdesc): New description table for 32-bit only DSP REV 1
and 2 builtins.
(bdesc_map): Add one field of unsupported_target_flags.
(bdesc_arrays):  Update entries to have extra fields.  Add
dsp_32only_bdesc.
(mips_init_builtins): Initialize new function types.
Check unsupported_target_fileds to filter out builtins.
* config/mips/mips.h (TARGET_CPU_CPP_BUILTINS): Define __mips_dspr2 if
TARGET_DSPR2.
(ASM_SPEC): Pass mdspr2 to the assembler.
