Correct `hIsReadable` and `hIsWritable` for duplex handles
This contribution implements CLC proposal #371. It changes `hIsReadable`
and `hIsWritable` such that they always throw a respective exception
when encountering a closed or semi-closed handle, not just in the case
of a file handle.

Fix determinism of linker arguments
The switch from Data.Map to UniqMap in 3b5be05ac29 introduced
non-determinism in the order of packages passed to the linker.
This resulted in non-reproducible builds where the DT_NEEDED entries in
dynamic libraries were ordered differently across builds.
Fix the regression by explicitly sorting the package list derived from
UniqMap.
Fixes #26838

determinism: Use a deterministic renaming when writing bytecode files
Now when writing the bytecode file, a counter and substitution are used
to provide deterministic keys to local variables (rather than relying on
uniques). This change ensures that `.gbc` are produced
deterministically.

ghc-internal: delete Version hs-boot loop
Version has a Read instance which needs Unicode but part of the Unicode interface is the unicode version. This is easy to resolve. We simply don't re-export the version from the Unicode module.

Linker: implement support for COMMON symbols (#6107)
Add some support for COMMON symbols. We don't support common symbols
having different sizes where the larger one is allocated after the
smaller one. The linker will fail with an appropriate error message if
it happens.

compiler: avoid unneeded traversals in GHC.Unit.State
Following !15591, this patch avoids unneeded traversals in
`reportCycles`/`reportUnusable` when log verbosity is below given
threshold. Also applies `logVerbAtLeast` when appropriate.

Hadrian: deprecate --bignum and automatically enable +native_bignum for JS
Deprecate --bignum=... to select the bignum backend. It's only used to
select the native backend, and this can be done with the +native_bignum
flavour transformer.
Additionally, we automatically enable +native_bignum for the JS target
because the GMP backend isn't supported.
