In assertOptimized and assertUnoptimized, we can optionally pass in the
function name. We also used to pass in an optional 'sync' parameter, to
decide whether to wait for background compilations to finish before
checking state.
The sync parameter was removed in favour of explicit intrinsics, so fix
callers of assertOptimized to no longer try to set it. Also, use
function.name as the function name when no name was passed.

This CL solves two problems:

CheckBigInt64 to CheckBigInt and CheckedBigIntToBigInt64.
- Having precise checks for SignedBigInt64 to make the range of BigInt64
consistent in CheckedBigInt64Ops and CheckedBigIntToBigInt64.
Otherwise, there would be semantic difference between the subgraphs
where we keep CheckBigInt64 inbetween two CheckedBigInt64Ops (e.g.,
the variant assert_types) and the subgraphs where we eliminate the
checks.

This CL adds TurboFan optimizations for length and element access
of TypedArrays and DataViews that are rab/gsab-backed.
To enable this optimization, this CL builds the necessary machinery

- Introduce Type::Machine() to allow the typer and the verifier to
provide a type to those machine operators in parts of the pipeline
that require nodes to be typed.
- Add EnterMachineGraph and ExitMachineGraph operators that define
the boundary between early machine graphs and the normal graph with

- Give Branch operators a BranchSemantics parameter to distinguish
between machine branches (condition is a machine level value) and
JS branches (condition is a JS boolean value) and have phases that
handle branches decide on the branch's semantics based on this
parameter instead of the position in the pipeline.
- Extend SimplifiedLowering and SimplifiedLoweringVerifier to handle
machine graphs. In particular, constants required special handling,
because they are cached in the graph but they may have uses in both
a machine and the JS graph, which prevents consistent typing of
them.
- Moved lots of logic from JSCallReducerAssembler into
[JS]GraphAssembler such that functionality can be shared between
different phases (e.g. JSNativeContextSpecialization and
JSCallReducer need to generate logic to compute a TypedArray's
byte length). Extended assembler interface in general with
additional TNode<> overloads.

GetIterator on object o consists of two steps:
1) iter = load o[#Symbol.Iterator]
2) call iter
For null / undefined step (1) throws an exception, meaning
step (2) is never reached. Up to this change, turbofan
deopts if for either of the two steps there isn't enough
feedback, meaning that we have a deopt loop for null and

assertEquals() compares objects by comparing each property for both
objects. This was done by using Object.keys() which however only returns
enumerable properties.
With this change also non-enumerable properties are compared.
Still, the comparison doesn't require the properties to be equal.
So, if one property is marked enumerable in one object but not the
other, the objects would still be considered equal.
This could be adapted in a follow-up CL if desired.
The prototype is still ignored for the comparison.

Load current Memory start/size off of the wasm instance when entering
fast calls, so they can use that info for whatever they need to do.
Fast calls from JS set the memory to null, and the memory does not
need to be piped from wasm to slow callbacks as wasm always calls
the fast function.
