Fixes #10920, an issue where GHCi bails out when started alongside a
file named Prelude.hs or Prelude.lhs (even empty file suffices).
The in-source Note [GHCi and local Preludes] documents core reasoning.
Supplementary changes:
* add debug traces for module lookups under -ddump-if-trace;
* drop stale comment in GHC.Iface.Load;
* reduce noise in -v3 traces from GHC.Utils.TmpFs;
* new test, which also exercizes HomeModError.

This patch changes mblock size to page size on wasm. It allows us to
simplify our wasi-libc fork, makes it much easier to test third party
libc allocators like emmalloc/mimalloc, as well as experimenting with
threaded RTS in wasm.

Ticket #24768 showed that the Simplifier was accidentally destroying
a join point. It turned out to be that we were sending a bottoming
join point to the top, accidentally abstracting over /other/ join
points.
Easily fixed.
