Automatically generated path that adds flag `REQUIRES_UNIFIED_BUILD = True` to `moz.build`
when the module governed by the build config file is not buildable outside on the unified environment.
This needs to be done in order to have a hybrid build system that adds the possibility of combing
unified build components with ones that are built outside of the unified eco system.

Inline `Set.prototype.has` in CacheIR when called with objects.
Implementing `MacroAssembler::hashObject()` on 32-bit platforms is difficult,
because it uses 64-bit operations, so we either have to allocate twice as much
registers for `Register64` or alternatively spill the values on the stack. For
now just punt and only support this optimisation on 64-bit platforms.

On some systems, uint_fast8_t may be as big as size_t! So the `static_assert(sizeof(aIndex) < sizeof(size_t))` could fail there. The better test here is to check for the expected type (uint_fast8_t).
Now, since uint_fast8_t can be bigger than 8 bits, we may as well choose it for variant sizes greater than 255, up to UINT_FAST8_MAX.
(The added parentheses help clang-format distinguish '<' for tests vs for templates.)

When advancing to Beta, we stop adding sentinels after serialized data
in IPC::Message objects. These sentinels would cause all Extract calls
to not reach the end of the message buffer on Nightly. This patch fixes
an assertion failure which can occur when extract calls fully empty the
buffer, and the finished iterator is advanced by 0 bytes.

This should improve the performance of large calls to AdvanceAcrossSegments
when using a very large BufferList, as we no longer need to iterate over each
element to find the destination when the call is closer to the end.
This will be used most frequently with the new footer code to seek to the end
of an IPC message to read out the footer.

This unfortunately requires a new method to be added to BufferList to
support truncating the buffer to a particular iterator.

This is much simpler and lets us tidy up the addProperty code more. It also makes
it easier to change ShapeTable for property maps in the future.
Lookup performance and memory usage appear to be similar for the two versions,
probably because ShapeTable used the same double-hashing algorithm and because
we can purge most ShapeTables on GC.

Allow using the MOZ_KnownLive function to get around it.
Use case is the following: I have an std::function member variable, and I want
that member to be able to capture `this`.
Using a strong reference creates a cycle and thus would leak. I know `this` to
always outlive the member, so it is fine to use a weak capture there.

WASI lacks of support many memory stuff like mmap, memory protections and etc, but
it has malloc so we can use it instead. Also, here we are stubbing out all
uses of the missing WASI memory functionality.

Also make CompactPair<A, B> a literal type if A and B are literal types,
and add MaybeStorageBase that ought to be used as a basis of MaybeStorage
in a follow-up patch.

A long standing issue is that MOZ_ASSERT and related don't print stack
traces in debug builds when they're directly or indirectly emitted from
non-libxul code. Moving WalkTheStack to mozglue alleviates the problem.
It's also not printing stack traces when emitted from C code (and for
some C third party libraries, we do redirect assert to MOZ_ASSERT),
which we solve by making the corresponding API available without C++
(which WalkTheStack being a static method of the nsTraceRefCnt class
didn't allow, or the use of a closure on Android).
This requires some adjustements to headers that indirectly assume that
Assertions.h includes ErrorList.h through nsError.h through nscore.h
through nsTraceRefcnt.h.
We also remove TestStackCrawl.cpp because it hasn't been built since
bug 158528, 19 years ago.
