StaticArrays forces recompilation of JLLs on Windows with Julia 1.8.1

[mkitti]

I’m also now tracking down some invalidations coming from CategoricalArrays that I found when using Gadfly:

CategoricalArrays forces OpenSpecFun_jll recompilation

Yes, because the only non-erroring conversion to nothing is the one in Base, so many times these invalidation fixes are just improvements.

What has me a bit concerned is that some of these methods in Base seem easy to accidentally invalidate.
