The per-module caches for subtype relations and type equivalences are
accessed from several background compile jobs, so these accesses must

The `Debugger.getScriptSource()` and `Debugger.getWasmBytecode()`
methods in the CDP return Wasm wire bytes as protocol::Binary, which is
send as Base64-encoded JSON string in the communication to the DevTools
front-end, and hence leads to either crashing the renderer that is being
debugged or the renderer that's running the front-end if we allow
arbitrarily huge Wasm byte sequences here. This CL introduces a limit,
based on the maximum allowed string length, to avoid the crash and
instead signal a proper error to the DevTools front-end.

Motivation:
The immediate-argument classes defined in function-body-decoder.h were
often adding an offset to the provided pc. This was inconsistent,
bug-prone, and counterintuitive. This CL imposes that all immediates
are passed as pc the start of the immediate argument they are parsing.
Some other smaller inconsistencies are fixed as well.

Changes:

src/wasm/:
- Enforce that all Immediates are passed the pc at the start of the
  argument they are parsing. Adapt all call sites.
- Remove unneeded offset arguments from two SIMD related immediates.
- Add a pc argument to all Validate functions for immediates instead
  of using the Decoder's current pc.
- Remove the (unused) pc argument from all Complete functions for
  immediates.
- Introduce Validate() for BranchOnExceptionImmediate.
- In WasmDecoder::Decode(), make sure len is updated before breaking out
  of the loop in case of a Validate() failure.
- Change the default prefix_len of DecodeLoadMem/DecodeStoreMem to 1.

wasm-interpreter.cc:
- Change the default prefix_len of ExecuteLoad/Store to 1.
- Adapt offsets in calls to Immediates.
- Remove redundant opcode_length argument from ExecuteSimdOp, use len
  in its place.

function-body-decoder-unittest.cc
- Adapt offsets in calls to Immediates.
- Introduce and use EXPECT_OK, as is done in other tests.

It turns out that Liftoff often needs to know the size of a value in
bytes. Currently we are loading the size_log_2 from an array and then
performing a shift by that amount. We can slightly speed this up by just
loading the correct value directly.

Drive-by: Use {int8_t} for the internal array, since all values will
easily fit in that range.

Each single branch in the switch was push a new value on the operand
stack, but the code for that was not shared.
This CL refactors this such that we only allocate once, and then modify
the new slot as needed.
This makes the generated code a lot smaller (771 bytes instead of 1052
bytes on x64), and hopefully also faster.

The current code for AssignRegisterOnReload starts the search at
the first interval instead of relying on the cached {current_interval_},
which seems to be a main cause for slow compile time in the linked
issue's test case. Moreover, it does not take into account live range
holes of the current range. This change uses FirstIntersection instead
which already handles both issues.
Since inactive ranges are sorted by their next start, we can also break
early from the loop.

This retrieves script name directly from StackFrameBase, bypassing
building of StackFrameInfo if one hasn't already been initialized,
thus avoiding computation of expensive properties that are not
required. This matches current behavior of GetScriptNameOrSourceURL()

Local type information was stored in the {WasmFullDecoder}, and a
pointer to that vector was handed to {WasmDecoder}. Since
{WasmFullDecoder} inherits from {WasmDecoder}, we can just move the
vector to the {WasmDecoder} class, and save an indirection and an
unnecessary nullptr check.

Drive-by: Rename {GetLocalType} to {local_type}, since it's a simple
accessor.
Drive-by 2: Move fields of {WasmDecoder} to the end of the class, as
mandated in the style guide.
Drive-by 3: Rename some locals in the 'let' decoding to make the meaning

... and extend JS node wrapper functionality.

Node wrappers now have accessors for value inputs and
context/control/effect/frame-state inputs. Accessors are typed,
although types aren't very meaningful so far (in current examples we
only distinguish between Object/HeapObject).

The following node kinds now take an additional feedback vector input,
and use the new node wrapper functionality above:

- CloneObject
- CreateLiteralArray
- CreateLiteralObject
- CreateLiteralRegExp
- GetIterator
- GetTemplateObject
- HasProperty
- LoadProperty
- StoreProperty
