compiler: Turn `FinderCache` into a record of operations so that GHC API clients can
have full control over how its state is managed by overriding `hsc_FC`.

Also removes the `uncacheModule` function as this wasn't being used by anything
since 1893ba12fe1fa2ade35a62c336594afcd569736e

Fixes #23604

Correct -Wpartial-fields warning to say "Definition" rather than "Use"

Fixes #24710.  The message and documentation for `-Wpartial-fields` were
misleading as (a) the warning occurs at definition sites rather than use
sites, and (b) the warning relates to the definition of a field independently
of the selector function (e.g. because record updates are also partial).

GHCi: Support local Prelude

Fixes #10920, an issue where GHCi bails out when started alongside a
file named Prelude.hs or Prelude.lhs (even empty file suffices).

The in-source Note [GHCi and local Preludes] documents core reasoning.

Supplementary changes:

 * add debug traces for module lookups under -ddump-if-trace;
 * drop stale comment in GHC.Iface.Load;
 * reduce noise in -v3 traces from GHC.Utils.TmpFs;
 * new test, which also exercizes HomeModError.

ci: Use nixpkgs-20.04-darwin channel for darwin toolchain

We are currently seeing a couple of errors on darwin machines after I
bumped the toolchain commit.

```

```

In theory this channel should be tested so it should work?
