This adds a simple counter to Turbofan that's incremented throughout the compilation, hopefully
frequently enough so we can use it to detect divergence and performance bugs.
In addition, we assert that this counter never gets too high. That's the equivalent of a simple
timeout, just more deterministic. The limitations on Turbofan input size should guarantee that
we never exceed this limit. Since we probably do exceed it rarely, this check is only a DCHECK and
intended to detect performance and divergence issues, but not supposed to be performed in release
builds.

In addition, this CL adds UMA stats to observe the real world distribution of the tick measurement.

Previously all RegExp calls went through Runtime_RegExpExec when --regexp-interpret-all was set.

This CL avoids the runtime overhead by calling into the interpreter directly from the RegExpExec Builtin when the regular expression subject was already compiled to ByteCode (i.e. after the first call).

This CL changes how the start and end address for the iteration are
retrieved from an std::vector that won't cause a failed assertion.

There are some std::vector implementations that contain bounds checks.
The string table iteration code uses an access like
{&young_strings_[young_strings_.size()]} to retrieve the end address
for an iteration. This results in a out of bounds exception on such a
std::vector implementation even though the "element" itself is not actually
accessed.

Original Commit Message:

    We had both jump slots and lazy compile slots in the same table. This
    increases the space per slot to the maximum of the two, even though we
    often do not use lazy compilation and could have smaller jump slots.
    This CL splits the two into two separate tables. The lazy compile table
    will only be created on demand, and will never be patched.
    The jump table now only contains jumps, and is more compact (which
    might improve performance because of improved locality).

On newer compilers the {operator delete} with explicit {size_t}
argument would be instantiated for {WasmInstructionBuffer} and used
in the destructor of {std::unique_ptr<WasmInstructionBuffer>}. The
{size_t} argument is wrong though, since the pointer actually points
to a {WasmInstructionBufferImpl} object.
The solution is to explicitly provide a {operator delete}, preventing
an implicitly generated {size_t} operator.

perfrunner returns a failure if the build timeouts at any point even if it's
successful after retries. It tries to surface up the timeout issue. Due to this,
some bots stay red consistently, and confuses the sheriffs.

This CL masks the timeouts if the suite succeeds in the end.

This CL adds a new FreeList strategy, that can be turned on by using
flag `--gc-freelist-strategy=2`. It uses a lot (about 50)
FreeListCategories instead of the 6 ones used in FreeListLegacy.
Allocation is done using a best-fit strategy. However, FreeListMany
could be subclassed in order to change the allocation strategy while
still using the same freelists.

Using this strategy is expected to reduce memory usage but to also
reduce allocation performances.

The context was not set during streaming compilation.
The initial upload is the original CL and patch set 1 is the fix.

If the lookup of the resolve property on the constructor throws, we
need to call IteratroClose before rejecting the promise.

This change is mostly mechanical, but it's worth mentioning a few
slightly interesting cases:
- A couple of field definitions didn't match the signedness of their
  corresponding accessors.
- The generated accessors for Smi data use Smi values directly, but
  usually we want C++ accessors to use ints instead. I added a macro
  that hides the generated Smi accessors and exposes int accessors,
  but we might consider generating int accessors directly.
- The data held in some fields is described in comments next to the
  accessor definition for those fields. With automatically generated
  accessors, those comments need a new home. In this change I put them
  in the Torque object definition, but I'm open to other suggestions.
- gen-postmortem-metadata couldn't find updated class definitions after
  they got split across multiple lines, so I changed its matching
  logic. (Ideally debug-support.cc should be a Torque compiler output
  rather than something that involves parsing C++ with regexes, but
  this makes it correctly report subclass relationships for now.)
- The end offsets generated by Torque were off by one from the values
  that would be generated by DEFINE_FIELD_OFFSET_CONSTANTS.

RepresentationChanger::GetTaggedPointerRepresentation did not handle
kCompressed cases correctly for BigInts. This led to a crash of BigInt
benchmarks in js-perf-test.
