Rollup merge of #74079 - nnethercote:session-globals, r=nikomatsakis
Eliminate confusing "globals" terminology.

There are some structures that are called "globals", but are they global
to a compilation session, and not truly global. I have always found this
highly confusing, so this commit renames them as "session globals" and
adds a comment explaining things.

Also, the commit fixes an unnecessary nesting of `set()` calls
`src/librustc_errors/json/tests.rs`
