CMSIS-DSP: Added ARM_MATH_AUTOVECTORIZE and AUTOVECTORIZE to cmake
...
It is to provide more control and to disable
intrinsics version of some kernels when the C code is simple enough to
benefit from vectorization.
Since the result is compiler dependent, this option is optional.
(And it is not yet added to the source files).
Compilation flags may have to be tuned (-O3 for instance ...)

CMSIS-DSP: DSP_Lib_TestSuite can be built with cmake.

DSP_Lib_TestSuite can be built with cmake and run on FVP.
Some issues with CMSIS-DSP cmake where discovered and corrected.
Comments added to arm_biqaud_cascade_df2T+f32 since the Neon version
must be initialized differently (and thus the corresponding test
in DSP_Lib_TestSuite will have to be updated to pass with Neon version).

CMSIS-DSP: Enable build with MSVC compiler.

The goal of this commit is to allow the build of CMSIS-DSP on Windows to
enable the use of the library from Python or Matlab.
The Python wrapper has also been simplified and is now using the
CMSIS-DSP directly without requiring specific include files or source files.

CMSIS DSP : Added a cmake build system

It is not replacing the current MDK and ArmDS projects.
It is a complementary way to build CMSIS-DSP.
Current version is supporting ARM AC6 compiler from ArmDS.
The result of the build can be run on a FVP for instance.
It could be extended to use different toolchain and build for different
targets.
The README.md in DSP folder is giving all the details.

Split rfft_fast_init_f32 into separate initializer functions.
...
The rationale here is that if the caller knows the size FFT they require
at compile time, only the look-up tables required for that size are
placed in the data segment (ROM). This saves between ~40k to ~80k of
ROM when only using a single FFT size.
