Initial implementation of tuples in type checking
...
This leaves in place a bunch of TODOs and likely many bugs - notably, I haven't tested codegen/layout at all here.

Implement obligation checking for the Eq ability
...
Every type can have `Eq.isEq` derived for it, as long as
- it does not transitively contain a function
- it does not transitively contain a floating point value
- it does not transitively contain an opaque type that does not support
`Eq`

Eagerly resolve obligations during solving
...
Replaces the previously-used `DeferredObligations` structure used for
accumulating and then acting over ability obligations during module
solving in favor of just the `ObligationCache`. The `ObligationCache`
stays alive for the entirety of a module solving and provides a
convenient mechanism for answering obligation queries with a backed
cache.
