Do not collect compile-time metrics for T21839r
...the testsuite doesn't handle this properly since it
also collects run-time metrics. Compile-time metrics
for this test are already tracked via T21839c.

Fix recompilation checking for multiple home units
The key part of this change is to store a UnitId in the
`UsageHomeModule` and `UsageHomeModuleInterface`.
* Fine-grained dependency tracking is used if the dependency comes from
any home unit.
* We actually look up the right module when checking whether we need to
recompile in the `UsageHomeModuleInterface` case.
These scenarios are both checked by the new tests (
multipleHomeUnits_recomp and multipleHomeUnits_recomp_th )
Fixes #22675

Augment target filepath by working directory when checking if module satisfies target
This fixes a spurious warning in -Wmissing-home-modules.
This is a simple oversight where when looking for the target in the
first place we augment the search by the -working-directory flag but
then fail to do so when checking this warning.
Fixes #22676

Use NodeKey rather than ModuleName in pruneCache
The `pruneCache` function assumes that the list of `CachedInfo` all have unique `ModuleName`, this is not true:
* In normal compilation, the same module name can appear for a file and it's boot file.
* In multiple home unit compilation the same ModuleName can appear in different units
The fix is to use a `NodeKey` as the actual key for the interfaces which includes `ModuleName`, `IsBoot` and `UnitId`.
Fixes #22677

Recompilation checking: Don't try to find artefacts for Interactive & hs-boot combo
In interactive mode we don't produce any linkables for hs-boot files. So
we also need to not going looking for them when we check to see if we
have all the right objects needed for recompilation.

Don't write o-boot files in Interactive mode
We should not be producing object files when in interactive mode but we
still produced the dummy o-boot files. These never made it into a
`Linkable` but then confused the recompilation checker.

Improve driver diagnostic messages by including UnitId in message
Currently the driver diagnostics don't give any indication about which unit they correspond to.
For example `-Wmissing-home-modules` can fire multiple times for each different home unit and gives no indication about which unit it's actually reporting about.
Perhaps a longer term fix is to generalise the providence information away from a SrcSpan so that these kind of whole project errors can be reported with an accurate provenance. For now we can just include the `UnitId` in the error message.
Fixes #22678

Key ModSummary cache by UnitId as well as FilePath
Multiple units can refer to the same files without any problem. Just
another assumption which needs to be updated when we may have multiple
home units.
However, there is the invariant that within each unit each file only
maps to one module, so as long as we also key the cache by UnitId then
we are all good.
This led to some confusing behaviour in GHCi when reloading,
multipleHomeUnits_shared distils the essence of what can go wrong.
Fixes #22679

Finder: Look in current unit before looking in any home package dependencies
In order to preserve existing behaviour it's important to look within the current component before consideirng a module might come from an external component.
This already happened by accident in `downsweep`, (because roots are used to repopulated the cache) but in the `Finder` the logic was the wrong way around.

Fix Lint check for duplicate external names
Lint was checking for duplicate external names by calling removeDups,
which needs a comparison function that is passed to Data.List.sortBy.
But the comparison was not a valid ordering - it returned LT
if one of the names was not external.
For example, the previous implementation won't find a duplicate in
[M.x, y, M.x].
Instead, we filter out non-external names before looking for duplicates.

CmmToC: fix CmmRegOff for 64-bit register on a 32-bit target
We used to print the offset value to a platform word sized integer.
This is incorrect when the offset is negative (e.g. output of cmm
constant folding) and the register is 64-bit but on a 32-bit target,
and may lead to incorrect runtime result (e.g. #22607).
The fix is simple: just treat it as a proper MO_Add, with the correct
width info inferred from the register itself.

compiler: fix handling of MO_F_Neg in wasm NCG
In the wasm NCG, we used to compile MO_F_Neg to 0.0-x. It was an
oversight, there actually exists f32.neg/f64.neg opcodes in the wasm
spec and those should be used instead! The old behavior almost works,
expect when GHC compiles the -0.0 literal, which will incorrectly
become 0.0.
