Tracking the context is not enough, as we might clear the context to
avoid repeatedly reentering the same context.
Also fix unittests that relied on the default microtask queue getting
automatically processed instead of the one of the current context.

This saves running through the graph and re-maintaining the schedule

I have also tested it with gcc-10 on x64 and it still fails.

As a workaround we can force the usage of macros in one line

This reverts commit d16eefe0f2.
It is not correct to check for node equality during the graph
construction phase, because we can have optimizations that will combine
same nodes. So it can happen that in wasm-compiler, the inputs to
shuffle are not the same, so we canonicalize using that knowledge that
it will not be the same, and allow indices > 15. But later we can have
optimizations that combine the 2 inputs (e.g. splat of the same
constants), and the instruction selector will see that the input nodes
are the same.

Add a new CRTP StaticCallInterfaceDescriptor class, which provides
static constexpr getters for a descriptor's registers, parameter counts,
and so on. Each CallInterfaceDescriptor subclass is changed to extend
StaticCallInterfaceDescriptor, with StaticCallInterfaceDescriptor itself
extending CallInterfaceDescriptor to still provide a dynamic lookup
where needed.
StaticCallInterfaceDescriptor provides a couple of customisation points,
where it reads its CRTP derived descriptor's static fields and
functions, with default fallbacks where appropriate. With these
customisation points, the definition of CallInterfaceDescriptor
subclasses is simplified to:
a) Providing parameter names (as before)
b) Providing parameter types (as before)
c) Optionally setting flags (like kNoContext or kAllowVarArgs) as
static booleans on the class.
d) Optionally providing a `registers()` method that returns a
std::array<Register, N> of registers that may be used for
parameters (if not provided, this defaults to the implementation
specific default register set).
Parameter registers (and register count) are automagically set based on
the number of parameters and number of given registers, with extra magic
to ignore no_reg registers (to reduce ia32 special casing). The
CallInterfaceDescriptorData is initialized based on these static
functions, rather than manual per-descriptor initializers.
This allows us to skip loading descriptors dynamically for CallBuiltin
in Sparkplug, and instead lets us use a bit of template magic to
statically set up arguments for the calls. Any other users of statically
known descriptors will also benefit, thanks to C++ picking the static
methods over the dynamic methods on the base class when available.
Because we can remove various virtual functions and trigger heavier
inlining of constantly known values, binary size slightly decreases with
this change.
Note that torque-generated descriptors are changed to use the same magic,
rather than having Torque-specific magic, for consistency.

The typing of br_table was relaxed in
https://github.com/WebAssembly/spec/pull/1305. Before, we had to compute
the greatest lower bound of all branch types and make sure that stack
values are subtypes of that type. Now, we have to check that the stack
values are subtypes of each individual branch. This makes a difference
only in polymorphic stacks, but greatly simplifies the code, especially
with the upcoming introduction of a much more complex type system in
wasm-gc.

The pointer compression cage is the virtual memory reservation
that all compressed pointers fall within. This CL splits pointer
compression into two modes: a per-Isolate cage and a shared cage
among multiple Isolates.
When multiple Isolates are sharing a cage, they can decompress
each others' pointers and share the same virtual memory range.

Make runtime-call-stats a compile-time flag. Disabling RCS saves roughly
1MB binary size on 64bit systems and yields minor performance
improvements.

The only valid way to define a GCed type T is by inheriting from
GarbageCollected<T>. Since this is prone to typos (see tests), add a
simple check that covers most interesting use cases.
The static assert covers
A -> B -> GarbageCollected<C>
The static assert does not cover
A -> B -> C -> GarbageCollected<B>
(In order to do so, we would need __direct_bases() support which is
not yet available for C++.)

Full GCs on non-main-frame context disposals show up on real-world web
workloads and often cause missed frames. Remove and let the regular
scheduler take over these workloads.
