Merge pull request #15422 from mipsopen-fwu:msa-dev

Browse Source 
* Added MSA implementations for mips platforms. Intrinsics for MSA and build scripts for MIPS platforms are added.

Signed-off-by: Fei Wu <fwu@wavecomp.com>

* Removed some unused code in mips.toolchain.cmake.

Signed-off-by: Fei Wu <fwu@wavecomp.com>

* Added comments for mips toolchain configuration and disabled compiling warnings for libpng.

Signed-off-by: Fei Wu <fwu@wavecomp.com>

* Fixed the build error of unsupported opcode 'pause' when mips isa_rev is less than 2.

Signed-off-by: Fei Wu <fwu@wavecomp.com>

* 1. Removed FP16 related item in MSA option defines in OpenCVCompilerOptimizations.cmake.
2. Use CV_CPU_COMPILE_MSA instead of __mips_msa for MSA feature check in cv_cpu_dispatch.h.
3. Removed hasSIMD128() in intrin_msa.hpp.
4. Define CPU_MSA as 150.

* 1. Removed unnecessary CV_SIMD128_64F guarding in intrin_msa.hpp.
2. Removed unnecessary CV_MSA related code block in dotProd_8u().

Signed-off-by: Fei Wu <fwu@wavecomp.com>

* 1. Defined CPU_MSA_FLAGS_ON as "-mmsa".
2. Removed CV_SIMD128_64F guardings in intrin_msa.hpp.
