eb04b2bfa9 Added N-dim submat selection with vectors
Currently, to select a submatrix of a N-dimensional matrix, it requires
two lines of code while only one line of code is required if using a 2D
array.

I added functionality to be able to select an N-dim submatrix using a
vector list instead of a Range pointer. This allows initializer lists to
be used for a one-line selection.

ddf0554fff Use colon in "%YAML:1.0" directive when persisting to YAML-files
In YAML 1.0 the colon is mandatory. See http://yaml.org/spec/1.0/#id2558635.

This also allows prior releases to read YAML files created with the current version.

c7cb116dc0 check FP16 build condition correctly
* use __GNUC_MINOR__ in correct place to check the version of GCC
  * check processor support of FP16 at run time
  * check compiler support of FP16 and pass correct compiler option
  * rely on ENABLE_AVX on gcc since AVX is generated when mf16c is passed
  * guard correctly using ifdef in case of various configuration
  * use v_float16x4 correctly by including the right header file

903789f7af use universal intrinsic for FP16
* use v_float16x4 (universal intrinsic) instead of raw SSE/NEON implementation
  * define v_load_f16/v_store_f16 since v_load can't be distinguished when short pointer passed
  * brush up implementation on old compiler (guard correctly)
  * add test for v_load_f16 and round trip conversion of v_float16x4
  * fix conversion error

7fef96be1e add 64F intrinsic in HAL NEON
* use universal intrinsic for accumulate series using float/double
  * accumulate, accumulateSquare, accumulateProduct and accumulateWeighted
  * add v_cvt_f64_high in both SSE/NEON
  * add test for conversion v_cvt_f64_high in test_intrin.cpp
  * improve some existing universal intrinsic by using new instructions in Aarch64
  * add workaround for Android build in intrin_neon.hpp

9678d48e1a 2-channel interleaved load/store for universal intrinsics (float only)
* Added 2-channel ops to match existing 3-channel and 4-channel ops

* v_load_deinterleave() and v_store_interleave()

* Implements float32x4 only on SSE (but all types on NEON and CPP)

* Includes tests

* Will be used to vectorize 2D functions, such as estimateAffine2D()
