The escape analysis is able to perform scalar replacement on JSArrays
with in-object properties (which currently only happens for subclasses
of the Array constructor), but the Deoptimizer didn't properly
materialized and initialized the values of the in-object fields so far.

This adds a new operator LookupSigned32HashStorageIndex, which is a
specialization of the general LookupHashStorageIndex for Map#get that
is used when TurboFan knows that the key is in Signed32 range.

This improves the execution time of the ARES6 Basic test locally by
around 5% and seems to make sense in general.

Use case: anonymous script with sourceMappingUrl. User can set
breakpoint in source with sourceUrl from sourceMap, we persist this
breakpoint in DevTools and on page reload breakpoint should be restored
correctly.

Debugger.setBreakpointByUrl method provides capabilities to set
provisional breakpoints and looks like best candidate for new "scriptHash"
argument.

I considered other options such as replacing scriptId with something
more persistent like "script-hash:script-with-this-hash-number" but it
looks more complicated and doesn't provide clear advantages.

Further optimize the

  new Array(n)

expressions by also inlining the backing store allocation into TurboFan
optimized code. Currently these backing store allocations cannot be
eliminated by escape analysis and can also not be optimized further by
the memory optimizer (i.e. no allocation folding and not write barrier
elimination) yet, but this can be done in follow-up CLs.

This yields another ~5% improvement on the ARES6 ML benchmark (steady
state).

Drive-by-fix: Add support for loops to the GraphAssembler. This was
necessary to implement the initialization loops in for the backing
store allocations in the EffectControlLinearizer.

The twodigit_t code path emitted a library call rather than
a hardware "div" instruction. This is because compilers are
playing it safe: "div" can overflow when the divisor is too
small. Our algorithm carefully avoids this though, so using
the hardware "div" instruction is safe.

This speeds up a microbenchmark by almost 50%.

The typical pattern for using BuildCCall was to create a stack-allocated array
of arguments, which was passed to BuildCCall. BuildCCall then would allocate
scratch space using WasmGraphBuilder::Buffer and copy the arguments into the
scratch space. This copy is unnecessary and also the use of Buffer can lead to
silently overwriting scratch space that may be used higher up the stack.

Now BuildCCall takes all of the functions parameters as arguments and stores
this directly in a stack-allocated buffer, avoiding the use of Buffer at all and
all its associated pitfalls.

Make calls like

  new Array(n)
  new A(n)

(where A is a subclass of Array) inlinable into TurboFan. We do this by
speculatively checking that n is an unsigned integer that is not greater
than JSArray::kInitialMaxFastElementArray, and then lowering the backing
store allocation to a builtin call. The speculative optimization is
either protected by the AllocationSite for the Array constructor
invocation (if we have one), or by a newly introduced global protector
cell that is used for Array constructor invocations that don't have an
AllocationSite, i.e. the ones from Array#map, Array#filter, or from
subclasses of Array.

Next step will be to implement the backing store allocations inline in
TurboFan, but that requires Loop support in the GraphAssembler, so it's
done as a separate CL. This should further boost the performance.

This boosts the ARES6 ML benchmark by up to 8% on the steady state,
and also improves monomorphic Array#map calls by around 20-25% on the
initial setup.

Currently, the transition elements kind operation invalidates the
elements of all other arrays. In particular, if we loop over matrix 
elements using two nested loops, and do possibly transitioning access 
a[i][j] in every iteration, we invalidate the load elimination state 
for the array 'a' because a[i][j] might transition elements kind 
for the 'a[i]' array. As a result, the 'a[i]' access cannot be 
hoisted from the inner loop.

With this CL, we figure out that transitioning 'a[i]' cannot affect 'a'
because we know that 'a' does not have the transition's source map.

In the micro-benchmark below, the time for summing up the elements of
100x100 matrix improves by factor of 1.7 (from ~340ms to ~190ms).

function matrixSum(a) {
  let s = 0;
  let rowCount = a.length;
  let columnCount = a[0].length;
  for (let i = 0; i < rowCount; i++) {
    for (let j = 0; j < columnCount ; j++) {
      s += a[i][j];
    }
  }
  return s;
}

// Setup the matrices:
// Smi elements.
