ENH: [3/7] enable multi-platform SIMD compiler optimizations
- Put `CCompilerOpt` in action through add two command line
arguments that passed directly to `CCompilerOpt`'s
parameters which explained as follows:
* `--cpu-baseline` minimal set of required optimizations,
default is 'min' which provides the minimum CPU features
that can safely run on a wide range of users platforms.
* `--cpu-dispatch` dispatched set of additional optimizations,
default is 'max-xop-fma4' which enables all CPU features,
except for AMD legacy features.
the new arguments can be reached from `build`, `build_clib`,
`build_ext`, if `build_clib` or `build_ext` are not specified
by the user the arguments of `build` will be used, which also
hold the default values.
- Activate the new compiler dispatcher that comes with `CCompilerOpt`,
through adding a hock inside `build_clib` and `build_ext`
that works as a filter taking any C source files ends with
`.dispatch.c` and pass it directly to `CCompilerOpt` and
then take returned objects and linked to the final C lib.
- Add a third command-line argument `--disable-optimization` which
explicitly disable the whole new infrastructure, also
It adds a new compiler definition called `NPY_DISABLE_OPTIMIZATION`.
when `--disable-optimization` is enabled the dispatch-able sources
that end with `.dispatch.c` will be treated as a normal
C sources, also due to this disabling any C headers that
generated by `CCompilerOpt` must guard it with `NPY_DISABLE_OPTIMIZATION`,
otherwise, it will definitely break the build.
- New auto-generated C header located at `core/include/numpy/_cpu_dispatch.h`,
the new header contains all definitions and headers of CPU features that
enabled according to specified configuration in `--cpu-baseline`
and `--cpu-dispatch`.
