There's no need to provide the compiler a bunch of stuff that it's
trivially going to optimize away anyway, and we'd rather the release
assert not mess with the optimizer's view of the code.

The compiler is not always able to remove these (always-successful)
checks, so we might as well help it along.

We're going to introduce some friend declarations in the next patch, and
this change makes doing so easier. It's also slightly less confusing.

This also uses MakeUniqueForOverwrite* in two places where we immediately copy
over the Buffer from a Span.
Adds move assignment operator as well.

These are the equivalent of std::make_unique_for_overwrite and std::make_unique_for_overwrite with fallible allocation.

The phrase "copy the error" is misleading, as the error type might not be
copyable, and it is never copied but moved. "Propagate" the error seems to
be a good term to describe this.

The `mozilla::IsPod<HashMapEntry` specialisation was only needed for the static
assertions in "js/src/frontend/NameCollections.h". Part 3 removed those, so we
can now also remove `mozilla::IsPod<HashMapEntry`.
Drive-by change:
- Remove no longer needed "mozilla/PodOperations.h" include in mfbt/HashTable.h.
- And then fix up previously transitively included files for RootingAPI.h,
jsfriendapi.h, and Bench.cpp.

MOZ_ALWAYS_TRUE() evaluates its expression in both debug and release builds. This bug will change MOZ_ALWAYS_TRUE() to use MOZ_DIAGNOSTIC_ASSERT() instead of MOZ_ASSERT(), so MOZ_DIAGNOSTIC_ALWAYS_TRUE() will be redundant.

RC should be non-copyable. It already is non-copyable in the atomic variant,
but not in the non-atomic variant. This ensures that RefCounted is also
non-copyable, which prevents that classes deriving from RefCounted get
accidentally copied.
Also, RC's operator= should be defined only in debug builds. As already
described in a code comment, it's only used in debug builds (to assign the
dead value), and otherwise no modifications other than incrementing &
decrementing should be possible.
