This commit converts the `vec_splats` functions in altivec.h to macros, solving an issue where `vec_splats` calls could not assign to variables of static storage duration, such as:

  static vector int x = vec_splats(1);

Since `vec_splats` was implemented as a function, code such as in this example <https://code.videolan.org/videolan/dav1d/-/blob/059ad248d6b8b5a6115875acd9631746c8c3dc34/src/ppc/looprestoration_init_tmpl.c#L55> would result in a compile-time error in `clang`. This differs from `gcc`, which allows this construct.

This updates tests accordingly, and fixes PR44276 and PR44455. Sorry for the delay in getting this to you.
