Detect MIPS DSP and DSPR2 programattically.

Detect MIPS DSP and DSPR2 programattically.

Procedure:

$ platform_tools/android/toolchains/ndk-r10c-mips-darwin_v14/bin/mipsel-linux-android-gcc -dM -E - < /dev/null | sort > vanilla.mips
$ platform_tools/android/toolchains/ndk-r10c-mips-darwin_v14/bin/mipsel-linux-android-gcc -mdsp -dM -E - < /dev/null | sort > dsp.mips
$ platform_tools/android/toolchains/ndk-r10c-mips-darwin_v14/bin/mipsel-linux-android-gcc -mdspr2 -dM -E - < /dev/null | sort > dspr2.mips

$ diff vanilla.mips dsp.mips
239a240,241
> #define __mips_dsp 1
> #define __mips_dsp_rev 1

$ diff vanilla.mips dspr2.mips
239a240,242
> #define __mips_dsp 1
> #define __mips_dsp_rev 2
> #define __mips_dspr2 1


So, defined(__mips_dsp) -> SK_MIPS_HAS_DSP, defined(__mips_dspr2) -> SK_MIPS_HAS_DSPR2.
