For each module in a GHCi session, we keep alive one `ModLocation`.
A `ModLocation` is fairly inefficiently packed, as `String`s are
expensive in memory usage.
While benchmarking the agda codebase, we concluded that we keep alive
around 11MB of `FilePath`'s, solely retained by `ModLocation`.
We provide a more densely packed encoding of `ModLocation`, by moving
from `FilePath` to `OsPath`. Further, we migrate the full `Finder`
component to `OsPath` to avoid unnecessary transformations.
As the `Finder` component is well-encapsulated, this requires only a
minimal amount of changes in other modules.
We introduce pattern synonym for 'ModLocation' which maintains backwards
compatibility and avoids breaking consumers of 'ModLocation'.

We have formally dropped i386 windows support (#18487) a long time
ago. The stdcall foreign call convention is only used by i386 windows,
and the legacy logic around it is a significant maintenance burden for
future work that adds arm64 windows support (#24603). Therefore, this
patch removes stdcall support completely from the compiler as well as
the RTS (#24883):
- stdcall is still recognized as a FFI calling convention in Haskell
syntax. GHC will now unconditionally emit a warning
(-Wunsupported-calling-conventions) and treat it as ccall.
- Apart from minimum logic to support the parsing and warning logic,
all other code paths related to stdcall has been completely stripped
from the compiler.
- ghci only supports FFI_DEFAULT_ABI and ccall convention from now on.
- FFI foreign export adjustor code on all platforms no longer handles
the stdcall case and only handles ccall from now on.
- The Win32 specific parts of RTS no longer has special code paths for
stdcall.
This commit is the final nail on the coffin for i386 windows support.
Further commits will perform more housecleaning to strip the legacy
code paths and pave way for future arm64 windows support.

This patch adjusts test cases to handle the stdcall removal:
- Some stdcall usages are replaced with ccall since stdcall doesn't
make sense anymore.
- We also preserve some stdcall usages, and check in the expected
warning messages to ensure GHC always warn about stdcall usages
(-Wunsupported-calling-conventions) as expected.
- Error code testsuite coverage is slightly improved,
-Wunsupported-calling-conventions is now tested.
- Obsolete code paths related to i386 windows are also removed.

In pursuit of: #22736.
This MR moves ad-hoc symbols used throughout the js backend into a
single symbols file. Why? First, this cleans up the code by removing
ad-hoc strings created on the fly and therefore makes the code more
maintainable. Second, it makes it much easier to eventually type these
identifiers.

This patch replaces the ad-hoc `MYTASK_USE_TLV` with the
`CC_SUPPORTS_TLS` macro. If TLS support is detected by autoconf, then
we should use that for managing `myTask` in the threaded RTS.

As a `ModIface` often contains duplicated values that are not
necessarily shared, we improve sharing by serialising the `ModIface`
to an in-memory byte array. Serialisation uses deduplication tables, and
deserialisation implicitly shares duplicated values.
This helps reducing the peak memory usage while compiling in
`--make` mode. The peak memory usage is especially smaller when
generating interface files with core expressions
(`-fwrite-if-simplified-core`).
On agda, this reduces the peak memory usage:
* `2.2 GB` to `1.9 GB` for a ghci session.
On `lib:Cabal`, we report:
* `570 MB` to `500 MB` for a ghci session
* `790 MB` to `667 MB` for compiling `lib:Cabal` with ghc
There is a small impact on execution time, around 2% on the agda code
base.

To reduce memory usage of `ModIface`, we serialise `ModIface` to an
in-memory byte array, which implicitly shares duplicated values.
This serialised byte array can be reused to avoid work when we actually
write the `ModIface` to disk.
We introduce a new field to `ModIface` which allows us to save the byte
array, and write it direclty to disk if the `ModIface` wasn't changed
after the initial serialisation.
This requires us to change absolute offsets, for example to jump to the
deduplication table for `Name` or `FastString` with relative offsets, as
the deduplication byte array doesn't contain header information, such as
fingerprints.
To allow us to dump the binary blob to disk, we need to replace all
absolute offsets with relative ones.
We introduce additional helpers for `ModIface` binary serialisation, which
construct relocatable binary blobs. We say the binary blob is relocatable,
if the binary representation can be moved and does not contain any
absolute offsets.
Further, we introduce new primitives for `Binary` that allow to create
relocatable binaries, such as `forwardGetRel` and `forwardPutRel`.

-------------------------
These metric increases may look bad, but they are all completely benign,
we simply allocate 1 MB per module for `shareIface`. As this allocation
is quite quick, it has a negligible impact on run-time performance.
In fact, the performance difference wasn't measurable on my local
machine. Reducing the size of the pre-allocated 1 MB buffer avoids these
test failures, but also requires us to reallocate the buffer if the
interface file is too big. These reallocations *did* have an impact on
performance, which is why I have opted to accept all these metric
increases, as the number of allocated bytes is merely a guidance.
This 1MB allocation increase causes a lot of tests to fail that
generally have a low allocation number. E.g., increasing from 40MB to
41MB is a 2.5% increase.
In particular, the tests T12150, T13253-spj, T18140, T18304, T18698a,
T18923, T20049, T24582, T5837, T6048, and T9961 only fail on i386-linux
job, where the number of allocated bytes seems to be lower than in other
jobs.
