API changes tracking

[DerThorsten]

this is just to keep track of the api changes I noticed while refactoring xtensor from xsimd7 to xsimd8

there are some trivial changes

    xsimd::load_simd    =>     xsimd::load;
    xsimd::store_simd  =>     xsimd::store;

And more complicated ones xsimd::set_simd is similiar to the new xsimd::broadcast but the new broadcast only takes one template argument.

...to be continued...

You meant xsimd::set_simd is similar to xsimd::broadcast, right?

[DerThorsten]

yes, ..edited it

We now have a https://github.com/xtensor-stack/xsimd/blob/master/Changelog.rst changelog to keep track of changes \o/
