Compatibility with 9.8.1 as boot compiler
This fixes several compatability issues when using 9.8.1 as the boot
compiler.
* An incorrect version guard on the stack decoding logic in ghc-heap
* Some ghc-prim bounds need relaxing
* ghc is no longer wired in, so we have to remove the -this-unit-id ghc
call.
Fixes #24077

NCG: Fix a bug in jump shortcutting.
When checking if a jump has more than one destination account for the
possibility of some jumps not being representable by a BlockId.
We do so by having isJumpishInstr return a `Maybe BlockId` where Nothing
represents non-BlockId jump destinations.
Fixes #24507

hadrian/bindist: Ensure that phony rules are marked as such
Otherwise make may not run the rule if file with the same name as the
rule happens to exist.

Fix haddock source links and hyperlinked source
There were a few issues with the hackage links:
1. We were using the package id rather than the package name for the
package links. This is fixed by now allowing the template to mention
%pkg% or %pkgid% and substituing both appropiatly.
2. The `--haddock-base-url` flag is renamed to `--haddock-for-hackage`
as the new base link works on a local or remote hackage server.
3. The "src" path including too much stuff, so cross-package source
links were broken as the template was getting double expanded.
Fixes #24086

rts/linker: Don't unload native objects when dlinfo isn't available
To do so is unsafe as we have no way of identifying references to
symbols provided by the object.
Fixes #24513. Fixes #23993.

linker: Avoid linear search when looking up Haskell symbols via dlsym
See the primary Note [Looking up symbols in the relevant objects] for a
more in-depth explanation.
When dynamically loading a Haskell symbol (typical when running a splice or
GHCi expression), before this commit we would search for the symbol in
all dynamic libraries that were loaded. However, this could be very
inefficient when too many packages are loaded (which can happen if there are
many package dependencies) because the time to lookup the would be
linear in the number of packages loaded.
This commit drastically improves symbol loading performance by
introducing a mapping from units to the handles of corresponding loaded
dlls. These handles are returned by dlopen when we load a dll, and can
then be used to look up in a specific dynamic library.
Looking up a given Name is now much more precise because we can get
lookup its unit in the mapping and lookup the symbol solely in the
handles of the dynamic libraries loaded for that unit.
In one measurement, the wait time before the expression was executed
went from +-38 seconds down to +-2s.
This commit also includes Note [Symbols may not be found in pkgs_loaded],
explaining the fallback to the old behaviour in case no dll can be found
in the unit mapping for a given Name.
Fixes #23415

rts: Make addDLL a wrapper around loadNativeObj
Rewrite the implementation of `addDLL` as a wrapper around the more
principled `loadNativeObj` rts linker function. The latter should be
preferred while the former is preserved for backwards compatibility.
`loadNativeObj` was previously only available on ELF platforms, so this
commit further refactors the rts linker to transform loadNativeObj_ELF
into loadNativeObj_POSIX, which is available in ELF and MachO platforms.
The refactor made it possible to remove the `dl_mutex` mutex in favour
of always using `linker_mutex` (rather than a combination of both).
Lastly, we implement `loadNativeObj` for Windows too.

Use symbol cache in internal interpreter too
This commit makes the symbol cache that was used by the external
interpreter available for the internal interpreter too.
This follows from the analysis in #23415 that suggests the internal
interpreter could benefit from this cache too, and that there is no good
reason not to have the cache for it too. It also makes it a bit more
uniform to have the symbol cache range over both the internal and
external interpreter.
This commit also refactors the cache into a function which is used by
both `lookupSymbol` and also by `lookupSymbolInDLL`, extending the
caching logic to `lookupSymbolInDLL` too.
