IPE data resulting from the `-finfo-table-map` flag may now be
compressed by configuring the GHC build with the
`--enable-ipe-data-compression` flag. This results in about a 20%
reduction in the size of IPE-enabled build results.
The compression library, zstd, may optionally be statically linked by
configuring with the `--enabled-static-libzstd` flag (on non-darwin
platforms)
libzstd version 1.4.0 or greater is required.

This prepares for having linear let expressions in the frontend.
When desugaring lets, SPECIALISE statements create more copies of a
let binding. Because of the rewrite rules attached to the bindings,
there are dependencies between the generated binds.
Before this commit, we simply wrapped all these in a mutually
recursive let block, and left it to the simplified to sort it out.
With this commit: we are careful to generate the bindings in
dependency order, so that we can wrap them in consecutive lets (if the
source is non-recursive).

Previously `shutdown_handler` would call `stg_exit` if the scheduler was
Oalready found to be in `SCHED_INTERRUPTING` state (or higher). However,
`stg_exit` is not signal-safe as it calls `exit` (which calls `atexit`
handlers). The only safe thing to do in this situation is to call
`_exit`, which terminates with minimal cleanup.
Fixes #23417.

This requires changing the recomp007 test because now cabal passes
`this-unit-id` to executable components, and that unit-id contains a
hash which includes the ABI of the dependencies. Therefore changing the
dependencies means that -this-unit-id changes and recompilation is
triggered.
The spririt of the test is to test GHC's recompilation logic assuming
that `-this-unit-id` is constant, so we explicitly pass `-ipid` to
`./configure` rather than letting `Cabal` work it out.

Previously the `+werror` transformer would only pass `-Werror` to GHC,
which does not ensure that the same is passed to the C compiler when
building the RTS. Arguably this is itself a bug but for now we will just
work around this by passing `-optc-Werror` to GHC.
I tried to enable `-Werror` in all C compilations but the boot libraries
are something of a portability nightmare.

This is used to determine what to link when using the interpreter.
For now it's only used by the JS interpreter but it could easily be used
by the native interpreter too (instead of extracting names from compiled BCOs).

This is an implementation of the deprecated exports proposal #134.
The proposal introduces an ability to introduce warnings to exports.
This allows for deprecating a name only when it is exported from a specific
module, rather than always depreacting its usage. In this example:
module A ({-# DEPRECATED "do not use" #-} x) where
x = undefined
---
module B where
import A(x)
`x` will emit a warning when it is explicitly imported.
Like the declaration warnings, export warnings are first accumulated within
the `Warnings` struct, then passed into the ModIface, from which they are
then looked up and warned about in the importing module in the `lookup_ie`
helpers of the `filterImports` function (for the explicitly imported names)
and in the `addUsedGRE(s)` functions where they warn about regular usages
of the imported name.
In terms of the AST information, the custom warning is stored in the
extension field of the variants of the `IE` type (see Trees that Grow for
more information).
The commit includes a bump to the haddock submodule added in MR #28

Bytecode instructions like PUSH_L (push a local variable) contain
an operand that refers to the stack slot. Before this patch, the
operand type was SmallOp (Word16), limiting the maximum stack
offset to 65535 words. This could cause compiler panics in some
cases (See #22888).
This patch changes the operand type for stack offsets from
SmallOp to Op, removing the stack offset limit.
