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.

hadrian: Generate HSC2HS_EXTRAS variable in bindist installation

We must generate the hsc2hs wrapper at bindist installation time since
it must contain `--lflag` and `--cflag` arguments which depend upon the
installation path.

The solution here is to substitute these variables in the configure
script (see mk/hsc2hs.in). This is then copied over a dummy wrapper in
the install rules.

Fixes #24050.

configure: Correctly set --target flag for linker opts

Previously we were trying to use the FP_CC_SUPPORTS_TARGET with 4
arguments, when it only takes 3 arguments. Instead we need to use the
`FP_PROG_CC_LINKER_TARGET` function in order to set the linker flags.

Actually fixes #24414

Namespacing for fixity signatures (#14032)

Namespace specifiers were added to syntax of fixity signatures:
  - sigdecl ::= infix prec ops | ...
  + sigdecl ::= infix prec namespace_spec ops | ...

To preserve namespace during renaming MiniFixityEnv type
now has separate FastStringEnv fields for names that should be
on the term level and for name that should be on the type level.

makeMiniFixityEnv function was changed to fill MiniFixityEnv in the right way:
 - signatures without namespace specifiers fill both fields
 - signatures with 'data' specifier fill data field only
 - signatures with 'type' specifier fill type field only

Was added helper function lookupMiniFixityEnv that takes care about
looking for a name in an appropriate namespace.

Updates haddock submodule.

rts: remove unused HAVE_C11_ATOMICS macro

This commit removes the unused HAVE_C11_ATOMICS macro. We used to have
a few places that have fallback paths when HAVE_C11_ATOMICS is not
defined, but that is completely redundant, since the
FP_CC_SUPPORTS__ATOMICS configure check will fail when the C compiler
doesn't support C11 style atomics. There are also many places (e.g. in
unreg backend, SMP.h, library cbits, etc) where we unconditionally use
C11 style atomics anyway which work in even CentOS 7 (gcc 4.8), the
oldest distro we test in our CI, so there's no value in keeping
HAVE_C11_ATOMICS.

Allow docstrings after exports

Here we extend the parser and AST to preserve docstrings following
export items. We then extend Haddock to parse `@since` annotations in
such docstrings, allowing changes in export structure to be properly
documented.

Bumps haddock submodule.

Really, these references should be via known-key names anyways. I have

additional needed refactoring.

Accept performance shifts from ghc-internal restructure

As expected, Haddock now does more work. Less expected is that some
other testcases actually get faster, presumably due to less interface
file loading. As well, the size_hello_artifact test regressed a bit when
debug information is enabled due to debug information for the new stub
symbols.

Expose GHC.Wasm.Prim from ghc-experimental

Previously this was only exposed from `ghc-internal` which violates our

base: Explicit dependency to workaround #24436

Currently `ghc -M` fails to account for `.hs-boot` files correctly,
leading to issues with cross-package one-shot builds failing. This
currently manifests in `GHC.Exception` due to the boot file for
`GHC.Internal.Stack`. Work around this by adding an explicit `import`,
ensuring that `GHC.Internal.Stack` is built before `GHC.Exception`.

See #24436.
