Merge Debugger::addGeneratorFrame into DebuggerFrame::setGenerator, and expand
the role of clearGenerator to fully undo the effect of setGenerator.
The association between a Debugger.Frame referring to a generator or async call
and the underlying generator object must be recorded in five separate places, as
a transaction: either all or present, or none are present. To ensure this is
true, this patch places sole responsibility for emplacing all those relations in
a single function (setGenerator), with another function to tear down those
relations (clearGenerator) as its inverse/antidote/complement/antagonist (in the
anatomical sense)/what-have-you.
Actually, when a Debugger.Frame is GC'd, we cannot reliably undo some of the
connections, and in fact can let the GC take care of those for us, so the
tear-down function clearGenerator is split into two overloads, one which is
suitable for use from a finalizer and the other which takes care of the entire
task.

Later in this patch series, we will be gathering up all the code to manage the
association between DebuggerFrame and AbstractGeneratorFrame objects into a pair
of functions, one to establish a relation and the other to tear it down. The
removeif method combines iteration and entry removal, but we would rather have
entry removal live next to the code that tears down the rest of the association.
In preparation for that, this changeset replaces the sole use of removeIf with
its (not very large) definition, so that the entry removal can be more readily
moved into another function.

The hand-written assembly for libffi on aarch64/windows doesn't emit
unwind information. If we ever tried to unwind through these functions,
they'd look like leaf functions, which is decidedly not true and would
cause great pain.
For whatever reason, the original aarch64 libffi functions used
x21/x22/x23/x24 as their (callee-saved) scratch registers. This
convention works on windows as well, but the unwind information on
windows mandates that we start saving callee-saved registers starting
from x19, rather than x21. Rather than rewriting the assembly to use
x19/x20 instead of x21/x22, which would be a large change, we chose
instead to simply save/restore extra registers in the prolog/epilog.
This change does make the stack frame sizes slightly bigger, but an
extra 16 bytes in libffi stack frames should not matter.
The `-TC` change is necessary to make the compiler play nicely with .asm
file suffixes.

Toolchains that support wasm threads will soon start relying on bulk
memory being available (as Chrome more or less ships both proposals
already). Currently we have bulk memory on Nightly under an ifdef,
but shared memory in all channels under a flag; as a result, we are
not compatible on non-Nightly with code that will soon come out of
these toolchains.
This patch keeps bulk memory enabled on Nightly but additionally
enables it on other channels if shared memory has been enabled by the
flag.
Mostly this is straightforward: we always enable decoding of bulk
memory operations, but will subsequently fail compilation for these
ops if bulk memory has not been enabled by the ifdef and shared memory
has not been enabled by the flag.
The only tricky part is really that the bulk memory proposal changes
the bounds checking for memory.init and table.init from eager to lazy,
so here the combinations of flags selects the bounds checking
behavior.
Once we ship bulk memory all of this complexity disappears.

Nursery objects can have slots buffers in the nursery or in malloc memory; tenured objects always have their slots buffers in malloc memory. When a nursery object has a pointer to a malloced buffer it is present in the Nursery::mallocedBuffers set. The patch checks whether an object is tenured when freeing its slots buffer because if so this tells us that its buffer is malloced and can't be in the nursery's mallocedBuffers set.
This also gets rid of a call to Nursery::isInside() call (linear in the number of nursery chunks) when we know the object is tenured and hence can't reference nursery memory.

Previously I rolled the malloc byte count into a total byte count for each zone but this may adversely affect GC scheduling (e.g. by triggering more non-incremental GCs because allocation volumes appear higher with this change). So that we can land this machinery without disturbing benchmarks too much, this patch splits out the new malloc memory accounting into a separate counter and uses the maxMallocBytes setting as the threshold (default value is 128MB vs 30MB for the GC heap threshold) and a growth factor of 2. This should make the behaviour closer to the original behaviour for now. We can go back and adjust the parameters later to obtain the desired behaviour.

When a Debugger.Frame refers to a generator/async call, the generator's script
must be marked as a debuggee, so that if the call is resumed, the
JSOP_AFTERYIELD bytecode is compiled to the instrumentation that re-associates
the extant Debugger.Frame with the new concrete frame.
This extends DebugScript with a new field `generatorObserverCount`, akin to
`stepperCount`, which tracks the number of Debugger.Frames referring to the
script if it is a generator script. This count is adjusted when the

A Debugger.Frame for a generator or async call continues to refer to the same
call across suspensions (awaits and yields). This means that, even as the
underlying concrete frames (InterpreterFrame, BaselineFrame) come and go, the
Debugger.Frame retains its relationship with a particular
AbstractGeneratorObject. When that generator is resumed, the Debugger.Frame
acquires the new concrete frame as its new referent.
Normally, when a stack frame is popped, if it had a Debugger.Frame with an
onStep handler, we decrement the frame's script's stepper count, since that
Debugger.Frame's onStep handler is obviously not going to fire any more; the
frame is dead. But in the case of a generator or async frame, the generator call
may be resumed at some point, so for such frames, we leave the script's stepper
count incremented until the generator call returns, throws, or otherwise exits
permanently.
This means that if a Debugger.Frame and its AbstractGeneratorObject are GC'd, we
must decrement the generator's script's stepper count. Of course, the script
itself may also be being GC'd, in which case we need not do anything.
This patch makes DebuggerFrame::clearGenerator solely responsible for dropping
the stepper count on generator frames. Since DebuggerFrame::finalize already
clears the frame's generator, this takes care of the stepper count automatically.

Since GetGeneratorObjectForFrame is a bit involved (it looks up the identifier
'.generator' on the scope chain) and not entirely reliable (it returns nullptr
between the GENERATOR and SETALIASEDVAR .generator opcodes), it's better to
simply fetch the generator from the DebuggerFrame, when one is available.
Since a DebuggerFrame has a generator exactly when there is an entry in
generatorFrames going the other direction, from generator to DebuggerFrame, this
means that Debugger::removeFromFrameMapsAndClearBreakpointsIn can actually do
its job reliably, which lets us remove certain kinky conditions in The Famous
Step Count Assertion of 1874.
In other cases, GetGeneratorObjectForFrame is the only option, and its flakiness
doesn't matter; document those a bit better.
