Auto merge of #46004 - michaelwoerister:cached-mir-wip-3, r=nikomatsakis
...
incr.comp.: Implement query result cache and use it to cache type checking tables.
This is a spike implementation of caching more than LLVM IR and object files when doing incremental compilation. At the moment, only the `typeck_tables_of` query is cached but MIR and borrow-check will follow shortly. The feature is activated by running with `-Zincremental-queries` in addition to `-Zincremental`, it is not yet active by default.

refactor how we extract outlives bounds from trait definitions
...
This new way is **slightly** less expressive (I would be shocked if it
affects any code, though) when it comes to higher-ranked bounds or a
few other weird tricks. But we don't handle those consistently
regardless, and the new way does not require normalization and is just
wildly simpler.
