Original change's description:
> [turboassembler] Introduce hard-abort mode
> 
> For checks and assertions (mostly for debug code, like stack alignment
> or zero extension), we had two modes: Emit a call to the {Abort}
> runtime function (the default), and emit a debug break (used for
> testing, enabled via --trap-on-abort).
> In wasm, where we cannot just call a runtime function because code must
> be isolate independent, we always used the trap-on-abort behaviour.
> This causes problems for our fuzzers, which do not catch SIGTRAP, and
> hence do not detect debug code failures.
> 
> This CL introduces a third mode ("hard abort"), which calls a C
> function via {ExternalReference}. The C function still outputs the
> abort reason, but does not print the stack trace. It then aborts via
> "OS::Abort", just like the runtime function.
> This will allow fuzzers to detect the crash and even find a nice error
> message.
> 
> Even though this looks like a lot of code churn, it is actually not.
> Most added lines are new tests, and other changes are minimal.

This is a part of larger cl https://chromium-review.googlesource.com/c/v8/v8/+/1144524
"Port canonicalizeLanguageTag and isStructuallyValidLanguageTag from JS to C++."

This is being separated out because:
1) this will unblock ftang's work
2) there is an increased memory usage issue report I'd like to understand before
   connecting IsStructurallyValidLanguageTag for widespread usage

The memory concern will be dealt with in a follow-up cl.

Also in this cl:
Fix to ignore the first tag when checking for duplicate subtags.

This CL simplifies the implementation of inlined DataView
methods in TurboFan. It removes the explicit exception handling,
and just deopts and relies on the baseline code to handle
exceptions instead.

It also adapts the DataView test files in mjsunit/compiler/
accordingly.

TestHeapRootsNotReadOnly was mistakenly checking for exceptions to the
rule by comparing the value of the root rather than the address. Since
several roots point to UndefinedValue, this meant that only one of the
matching roots had to be in the list.

This fixes it by instead getting a Handle from Factory and using the
address() method to check whether the roots match the exception list.

Also adds detached_contexts, feedback_vectors_for_profiling_tools,
microtask_queue, serialized_global_proxy_sizes and serialized_objects to
the exception list now that the test is working properly.

This is a preparatory CL that refactors the WASM memory allocation path,
the WasmGraphBuilder, and several points of contact for ArrayBuffers to
allow them to eventually be up to 4GiB.

1.) Refactor definition of constants to prepare for memories of size 2^32
2.) Refactor WasmInstanceObject fields memory_size and memory_mask to
    be stored as uintptr_t
3.) Refactor WasmGraphBuilder to use 64-bit comparisons for bounds checks
4.) Refactor JSArrayBuffer accessor methods to use size_t properly.
5.) Add empirical maximum memory and array buffer size tests
