Additionally a bug in the wasm-to-C wrapper got fixed, which caused
problems with the thread-in-wasm flag: An invalid effect-chain got
constructed. With the write of the thread-in-wasm flag not being
properly placed in the effect chain, the write got scheduled too late.

Some cctests set the FLAG_stack_size in the TEST() macro which is run
after the cctest runner initializes the main isolate. The flag is only
used during isolate initialization, so this did not have any effect.
This fixes it by using the UNINITIALIZED_TEST() macro, creating the
isolate after setting the flag and passing it through to the WasmRunner.
See also https://crrev.com/c/2862778 which fixes JS cctests.

if (!ref.has_value()) return {}; // bailout

To enforce W^X for the WebAssembly code space, we want to explore using
Intel memory protection keys for userspace, also known as MPK, PKEYs, or
PKU. Instead of flipping page protection flags with mprotect (which
incurs a high syscall overhead; and which switches flags for the whole
process), this associates a key with each page once, and then changes
the permissions of that key with a fast thread-local register write.
That is, this gives both finger-grained permissions (per-thread) and

This CL is starts experimenting with PKUs by
(1) trying to allocate a protection key once per {WasmEngine} in x64
Linux systems, and
(2) adding a counter for recording the sucess/failure of that, to assess
the support for PKUs on the target machine.
The low-level PKU allocating functions should be moved into base/platform
long-term, but are inside wasm/ for this CL.

Using the default cctest TEST(...) macro causes later writes to
FLAG_stack_size to have no effect, because the StackGuard reads
that flag's value during Isolate initialization, which is done
before the test body is executed. This patch changes the two
existing tests that accidentally did this to UNINITIALIZED_TEST,
putting them in charge of Isolate creation, thereby ensuring that
the intended stack size is configured correctly.

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.

Previously we'd attach source positions to implicit returns that are
generated when leaving an async function with a promise rejection. This
was due to the use of `kNoSourcePosition` on the `end_position` in the
`ReturnStatement` nodes as indicator to pick the return position from
the function literal, instead of really not putting a source position on
that specific `Return` bytecode.
This CL adds a dedicated marker to `ReturnStatement` to express that the
`BytecodeGenerator` should put the return position from the function
literal there instead of overloading the meaning of `kNoSourcePosition`.

Map::HasOnlyStablePrototypesWithFastElements and
Map::SerializeForElementStore were asking if the prototype was a
JSObject but they were doing so with the original map on every loop
iteration instead of the current prototype's map.
Also, we can change it so that instead of using the underlying data
to check if it was a JSObject, but we can get the same information
reading the map's instance_type directly.
