This patch fixes FinalizationRegistry related logic for Cloudflare
Workers in wasm backend js post linker. Cloudflare Workers doesn't
support FinalizationRegistry, in this case we use a dummy
implementation that doesn't do anything.

(cherry picked from commit bea8ea4c)

This patch fixes setImmediate() implementation for Cloudflare Workers
in the wasm backend's js prelude script. Cloudflare Workers doesn't
support the MessageChannel API, and we use a setTimeout() based
fallback implementation in this case.

The executable wrappers are handled by hadrian and bindist Makefile.
The various .wrapper scripts in the tree are unused since removal of
Make build system, so this patch removes them all.

(cherry picked from commit 9ede97f3)

This patch cleans up obsolete CPP guarded code paths from the tree.
The minimum supported boot GHC version is 9.6, and all the pre-9.6 era
code paths can be removed.

(cherry picked from commit a55adc8e)

This patch removes unused `USE_REPORT_PRELUDE` code paths from the
tree. They have been present since the first git revision
4fb94ae5, and might have been useful
for debugging purposes many years ago, but these code paths are never
actually built. Removing these ease maintenance of relevant modules in
the future, and also allows us to get rid of `CPP` extension in those
modules as a nice byproduct.

(cherry picked from commit 573cad4b)

This patch removes unused `hscDecls`/`hscDeclsWithLocation` functions
from the compiler, to reduce maintenance burden when doing
refactorings related to ghci.

(cherry picked from commit e3496ef6)

This patch fixes the wasm backend JSFFI prelude script to avoid
calling `import("node:timers")` on non-deno hosts. Safari doesn't like
it and would print an error message to the console. Fixes
https://gitlab.haskell.org/ghc/ghc-wasm-meta/-/issues/13.

This patch enables late-CCS for perf flavour so that the testsuite can
pass for perf as well. Fixes #25308.

(cherry picked from commit 1bdb1317)

This patch adds `--max-old-space-size=8192` to wasm dyld shebang
arguments to bump V8 heap size limit. The default limit
(`heap_size_limit` returned by `v8.getHeapStatistics()`) is
dynamically determined and a bit too low under certain workloads, and
V8 would waste too much CPU time to garbage collect old generation
heap more aggressively. Bumping the limit to 8G doesn't imply dyld
would really take that much memory at run-time, but it lessens V8 heap
stress significantly.

Ben Gamari authored 6 months ago and Zubin committed 5 months ago

Here we verify the previously informal invariant that stable release
version numbers must have three components, preventing costly failed
releases.

Specifically, the check fails in the following scenarios:

 * `version=9.13` while `RELEASE=YES` since this would imply a
   release made from an unstable branch
 * `version=9.13.0` since unstable versions should only have two
   components
 * `version=9.12` since this has the wrong number of version components
   for a stable branch

Fixes #25390.
