This is necessary to make `SptEntry` serializable, as a part of the grand plan of serializable bytecode.

HasHscEnv is modelled on HasDynFlags. My first idea was to simply add thNameToGhcNameHsc and thNameToGhcNameTc, but those would been exactly the same as thNameToGhcName already.

On POSIX hosts the behavior is identical to :!, but on Windows it uses the msys2 shell instead of system cmd.exe shell. This is convenient when writing simple ghci scripts that run simple POSIX commands, and the behavior can be expected to be coherent on both Windows and POSIX.

The wasm dyld is refactored to take advantage of LoadDLLs and harvest background parallelism. On other platforms, LoadDLLs is based on a fallback codepath that does sequential loading. The driver is not actually emitting singular LoadDLLs message with multiple DLLs yet, this is left in subsequent commits.

We leverage these changes to remove the ad-hoc treatment of linearity of data constructors with 'dataConDisplayType' and 'dataConNonLinearType'. This is now handled by the machinery of 'pprWithInvisibleBits'.

Previously instruction dispatch is done by a classic switch loop, so executing the next instruction requires two jumps: one to the start of the switch loop and another to the case block based on the instruction tag. By using computed goto, we can build a jump table consisted of code addresses indexed by the instruction tags themselves, so executing the next instruction requires only one jump, to the destination directly fetched from the jump table.

If a user enables `-fprefer-byte-code`, then if a package provides a bytecode library, that will be loaded and used to satisfy the dependency. The main change is to separate the relevant parts of the `LoaderState` into external and home package byte code. Bytecode is loaded into either the home package or external part (similar to HPT/EPS split), HPT bytecode can be unloaded. External bytecode is never unloaded. The unload function has also only been called with an empty list of "stable linkables" for a long time. It has been modified to directly implement a complete unloading of the home package bytecode linkables. At the moment, the bytecode libraries are found in the "library-dirs" field from the package description. In the future when `Cabal` implements support for "bytecode-library-dirs" field, we can read the bytecode libraries from there. No changes to the Cabal submodule are necessary at the moment. Four new tests are added in testsuite/tests/cabal, which generate fake package descriptions and test loading the libraries into GHCi.

This starts accumulating a lot of `UnlinkedBCO` and memory over time. However, the `Linkable` is merely used to later record its usage in `mkObjectUsage`, which is used for recompilation checking. However, this is incorrect, as the interface file and bytecode objects could be in different states, e.g. the interface changes, but the bytecode library hasn't changed so we don't need to recompile and vice versa. By computing a `Fingerprint` for the `ModuleByteCode`, and recording it in the `LinkableUsage`, we know precisely whether the `ByteCode` object on disk is outdated. Thus, parts of this commit just makes sure that we efficiently compute a `Fingerprint` for `ModuleByteCode` and store it in the on-disk representation of `ModuleByteCode`. We change the `LoaderState` to retain `LinkableUsage`, which is smaller representation of a `Linkable`. This allows us to free the unneeded fields of `Linkable` after linking them. We declare the following memory invariants that this commit implements: * No `LinkablePart` should be retained from `LoaderState`. * `Linkable`s should be unloaded after they have been loaded. These invariants are unfortunately tricky to automatically uphold, so we are simply documenting our assumptions for now. We introduce the `linkable-space` test which makes sure that after loading, no `DotGBC` or `UnlinkedBCO` is retained. ------------------------- Metric Increase: MultiLayerModulesTH_OneShot ------------------------- We allocate a bit more, but the peak number of bytes doesn't change. While a bit unfortunate, accepting the metric increase. We add multiple new performance measurements where we were able to observe the desired memory invariants. Further, we add regression tests to validate that the recompilation checker behaves more correct than before.

Conceptually, we insert HPC ticks into the bytecode similar to how we insert breakpoints. HPC and breakpoints do not share the same tick array but we use a separate tick-array for hpc/breakpoint ticks during bytecode generation. We teach the bytecode interpreter to handle hpc ticks. The implementation is quite trivial, simply increment the counter in the global hpc_ticks array for the respective module. This hpc_ticks array is generated as part of the `CStub`, so we can rely on it existing. A tricky bit is "registering" a bytecode object for HPC instrumentation. In the compiled case, this is achieved via CStub and initializer/finalizers `.init` sections which are called when the executable is run. After the initializers have been invoked, which is before `hs_init_ghc`, we then call `startup_hpc` in `hs_init_ghc` iff any modules were "registered" for hpc instrumentation via `hs_hpc_module`. Since bytecode objects are loaded after starting up GHCi, this workflow doesn't work for supporting `hpc` and the `hpc` run-time is never started, even if a module is added for instrumentation. We fix this issue by employing the same technique as is for `SptEntry`s: * We introduce a new field to `CompiledByteCode`, called `ByteCodeHpcInfo` which contains enough information to call `hs_hpc_module`, allowing us to register the module for `hpc` instrumentation`. * After registering the module, we unconditionally call `startupHpc`, to make sure the .tix file is written. Calling `startupHpc` multiple times is safe. Calling `hs_hpc_module` multiple times for the same module is also safe. If we didn't register the hpc module in this way, evaluating a bytecode object instrumented with `-fhpc` without registering it in the `hpc` run-time will simply not generate any `.tix` files for this bytecode object. However, this shouldn't happen if everything is set up correctly.
