WebAssembly dynamic tiering should be tested with an origin trial. For
the origin trial the feature flag value has to be loaded from blink.
This CL stores the value of the --wasm-dynamic-tiering flag in the
compilation state, from where it gets passed forward to all uses of the
flag. The flag value gets loaded from blink when a new NativeModule is
created.

With dynamic tiering, typically not all functions of a WebAssembly
module get compiled with TurboFan, and therefore the code caching would
never get triggered. With this CL code caching is triggered whenever
{FLAG_wasm_caching_threshold} bytes of TurboFan code are generated.

This new caching event is only triggered when --wasm-dynamic-tiering is
enabled.

A mov can be up to 10 bytes, 6 for displacement, 4 for instr. Other
instructions (like pshufb) with a complex addressing mode can take 10
bytes too. So adjust the padding for disassembly of hex accordingly.
This requires fixing up all the test cases too.

The error showed when printing the resulting code object, because the
tier was neither TurboFan nor Liftoff, even though the code was
registered as a standard wasm function (instead of an import wrapper).

The {wasm_kind} is completely unused, thus remove it before fixing a
wrong {CodeKind} for wasm-to-js functions.

The Merge node for merging exceptions into the catch environment had
type kWord32, which is not a reference type. Because of this the GC does
not visit it and can collect it too early. Change the type to
kTaggedPointer.
Also change the type of ExceptionLocation() from IntPtr to TaggedPointer
for consistency. This one does not affect correctness because the
IfException node is already marked as tagged.

Do not require the --verify-heap flag to test aborting evacuation of a
page but randomly abort evacuation in debug builds with
--stress-compaction. This is intended to increase test coverage of this
mechanism.
