As of https://crrev.com/c/2629465, Simd tests cannot pass on
architectures without Simd support. Tests will need to be re-enabled
once Simd support is fully implemented on PPC.

This change completes support for import assertions for dynamic import().
A new version of the HostImportModuleDynamically callback taking import
assertions is added to the public API. The name is very verbose; we
could consider removing the "ImportAssertions" part when the old API
is removed.
Bytecode generation is updated to pass the assertions, if present, to
Runtime_DynamicImportCall.
Isolate::RunHostImportModuleDynamicallyCallback extracts the assertions
from the options bag, filters out the assertions not present in the
list specified by the host in HostGetSupportedImportAssertions, and
sorts them by code point order of the keys per
https://tc39.es/proposal-import-assertions/#sec-import-call-runtime-semantics-evaluation.
The resulting array is passed to the host in the callback.

First step towards the new exception handling proposal:
https://github.com/WebAssembly/exception-handling/issues/125
This is essentially a revert of:
"[wasm] Switch to new 'catch' and 'br_on_exn' proposal."
The changes are:
- "catch" instruction takes a tag immediate,
- "rethrow" instruction takes a label immediate,
- Add "catch_all" instruction,
- Remove "br_on_exn" instruction,
- Do not push exceptions on the stack, only the encoded values

The index to be traced can be a full (platform-dependent) pointer sized
integer now. This CL prepares memory tracing for that.
As a drive-by, the "address" field is renamed to "offset", or
"effective_offset", depending on the situation.

This is a reland of 0ba115e6a9
Changes compared to last reland:
- Fix Python code trying to write to expected_outcomes, which is now a
computed property.
- Fix remaining place in d8.cc that ignored the --fuzzing flag.
- Expect flag contradictions for --cache in code_serializer variant.

Previously, all ThisExpression's had kNoSourcePositions leading to
incorrect error messages like this:
➜ d8 -e "function t() { for (const x of this) {} } t();"
unnamed:1: TypeError: undefined is not a function
function t() { for (const x of this) {} } t();
^
TypeError: undefined is not a function
at t (unnamed:1:11)
at unnamed:1:43
This patch allows creation of a ThisExpression with a source position,
leading to a better error message:
➜ d8 -e "function t() { for (const x of this) {} } t();"
unnamed:1: TypeError: this is not iterable
function t() { for (const x of this) {} } t();
^
TypeError: this is not iterable
at t (unnamed:1:32)
at unnamed:1:43
This patch does not remove the existing cached version of
ThisExpression and instead creates a new one when required.

This is a reland of b8f9166664
Difference to previous CL: Additional functionality to specify
incompatible flags based on GN variables and extra-flags, used
to fix the issues that came up on the waterfall.
This also changes the rules regarding repeated flags: While
explicitly repeated flags are allowed for boolean values as long
as they are identical, repeated flags or explicit flags in the
presence of an active implication are disallowed for non-boolean
flags. The latter simplifies specifying conflict rules in
variants.py. Otherwise a rule like
INCOMPATIBLE_FLAGS_PER_EXTRA_FLAG = {
"--gc-interval=*": ["--gc-interval=*"],
}
wouldn't work because specifying the same GC interval twice
wouldn't actually count as a conflict. This was an issue with
test/mjsunit/wasm/gc-buffer.js, which specifies
--gc-interval=500 exactly like the extra flag by the stress bot.
Also, this now expands contradictory flags checking to d8 flags
for consistency.

The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.
With this change, mjsunit tests pass on x64.
The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.
Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.

The interpreter will be moved to be test-only, hence
--wasm-interpret-all also needs to be removed.
Since we don't have any non-compiling tier any more, we also remove the
implication from --jitless to --wasm-lazy-compilation. Instead, we add
another CHECK that we can't be in jitless mode if we trigger any wasm
compilation.
All tests that just ran other tests and additionally passed
--wasm-interpret-all become redundant and are deleted. Also all
regression tests that explicitly specify --wasm-interpret-all are not
needed any more.

To avoid shrinking the unregister token map on each pop of the cleared
cell list, the Torque implementation of the cleanup loop avoids
shrinking the map until the end of the loop.
To support that, PopClearedCellHoldings is refactored to the Torque
PopClearedCell which calls the
JSFinalization::RemoveCellFromUnregisterTokenMap and the runtime
ShrinkFinalizationRegistryUnregisterTokenMap. The former cannot GC is
and is implemented in CSA as a fast C call. The latter can GC and is a
runtime call.
This also incidentally makes uses of FinalizationRegistry without
unregister token a fast path that doesn't have to leave Torque.

The source position is set to the function call (console.log) not the
spread (..x), in the bytecode generator, as the spread operation is
done as part of the CallWithSpread bytecode.
The CallPrinter stops at the function call and doesn't look at the
arguments as well (in CallPrinter::VisitCall) to see if the error is
from an incorrect spread operation.
With this patch, we pass some state to the CallPrinter in the
CallWithSpread error case and check that in CallPrinter::VisitCall
before returning.
For the given source string:
```
x = undefined;
console.log(1, ...x);
```
Previously, the error was -
```
test.js:2: TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))
console.log(1, ...x);
^
TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))

```
Now, the error is -
```
_test.js:2: TypeError: x is not iterable (cannot read property undefined)
console.log(1, ...x);
^
TypeError: x is not iterable (cannot read property undefined)
at _test.js:2:9
