Deprecate -Wsemigroup

This warning was used to prepare for Semigroup becoming a superclass
of Monoid, and for (<>) being exported from Prelude. This happened in
GHC 8.4 in 8ae263ceb3566 and feac0a3bc69fd3.

The leftover logic for (<>) has been removed in GHC 9.8, 4d29ecdfcc79.
Now the warning does nothing at all and can be deprecated.

Fix loopification in the presence of void arguments

This also removes Note [Void arguments in self-recursive tail calls],
which was just misleading.  It's important to count void args both
in the function's arity and at the call site.

Fixes #24295.

driver: Set -DPROFILING when compiling C++ sources with profiling

Earlier, we used to pass all preprocessor flags to the c++ compiler.
This meant that -DPROFILING was passed to the c++ compiler because
it was a part of C++ flags
However, this was incorrect and the behaviour was changed in
8ff3134ed4aa323b0199ad683f72165e51a59ab6. See #21291.

But that commit exposed this bug where -DPROFILING was no longer being passed
when compiling c++ sources.

The fix is to explicitly include -DPROFILING in `opt_cxx` when profiling is
enabled to ensure we pass the correct options for the way to both C and C++
compilers

Fixes #24286

Make TYPE and CONSTRAINT not-apart

Issue #24279 showed up a bug in the logic in GHC.Core.Unify.unify_ty
which is supposed to make TYPE and CONSTRAINT be not-apart.

Easily fixed.

GHCi: Lookup breakpoint CCs in the correct module

We need to look up breakpoint CCs in the module that the breakpoint
points to, and not the current module.

Fixes #24327
