Rollup merge of #133847 - nnethercote:rm-Z-show-span, r=compiler-errors

Browse source 
Remove `-Zshow-span`.

It's very old (added in #12087). It's strange, and it's not clear what its use cases are. It only works with the crate root file because it runs before expansion. I suspect it won't be missed.

r? `@estebank`
