Collect type feedback in the bytecode handler for 'new' bytecode. The
earlier cl (https://codereview.chromium.org/2153433002/) was reverted
because that implementation did not collect allocation site feedback.
This regressed delta blue by an order of magnitude. This implementation
includes collection of allocation site feedback.

This adds the possibility to address test cases in the
status file with the variant under which the test is running.
This is only allowed in top-level sections.
Example:
[{
'test-case': [PASS, SLOW],
}]
['variant == foo', {
'test-case': [FAIL],
}]
The test case "test-case" is marked as slow in all variants.
Additionally, in variant foo, it'll be expected to fail.
This CL also exemplifies the new feature with test cases
running under the ignition_turbofan variant. The
corresponding legacy flag is deprecated.

The flag was introduced for ignition development. It can only
be used when running ignition tests in isolation on the bots.
The bots only use ignition_turbo in isolation since a while
and don't pass the --ignition flag anymore.

This adds preliminary support for on-stack replacement from Ignition to
optimized code generated by TurboFan to the runtime profiler. Involved
heuristics (e.g. code size allowance) have been taken from existing code
without any re-evaluation in the new setting.

This CL more or less reverts commit https://codereview.chromium.org/2107733002/
The use of the MathPow code stub that was introduced by that commit caused
problems on arm64, and the MathPow code stub was also an obstacle in the
implementation of parallel code generation.
In addition this CL turns on the mjsunit/wasm/embenchen tests for arm64
which were turned off because of problems with MathPow on arm64.

In int32 multiplication, if we have a positive integer as input, then we know we can't produce a -0 answer. The same is true if truncation is applied (x * y | 0). Without this information, we have to rather annoyingly check if the result of multiplication is 0, then OR the inputs to check for negativity, and possibly return -0. In TurboFan, we'll deopt in this case.

This makes sure the {AstGraphBuilder} respects the catch-prediction that
is provided by the parser along with each {TryStatement}. This is needed
for try-blocks materialized by the parser not to influence predictions
users expect when using the debugger.

This removes the checking for use-def and def-use chain links from the
graph verification. Presence of such links can only be violated by a bug
in the actual {Node} implementation itself. That container class is also
covered by unit tests.
The verification in question was useful in the early days when the graph
implementation itself was prone to bugs. By now it has stabilized and
spending O(n^2) time during graph verification is too wasteful to still
be considered a reasonable trade-off.

While the test was useful to reproduce the issue locally it creates a lot of
heap pressure and causes all sorts of troubles (OOM, slowness) on the bots, so
let's drop it.

The dependency would only happen if we have a smi overflow for the length and
have create a heap number. In this case the heap number would've to survive
until the array buffer is collected.
To avoid this dependency we track the length (as we previously used to).

The re-typer now only types a node if its inputs are all typed with the
exception of phi nodes. This works because all cycles in the graph have
to contain a phi node.

A pointer comparison on the effect path states is not sufficient to
guarantee termination; we really need to check the actual nodes to
make sure we terminate properly, similar to what BranchElimination
does.

These simplified operators are used to perform the hole checks when
loading elements from a holey array. Depending on the CheckHoleMode,
they either return the hole as undefined or some NaN, or deoptimize
if the value is the hole or the hole NaN.

to only run it with turbofan.
