Port commit e50d19cb

Original Commit Message:

    https://crrev.com/c/3471854 already disabled the RecordWrite builtin
    specifically for incremental marking. Since this didn't regress performance as expected, we can now remove those versions of the
    builtin.

    This will simplify the barrier implementation a bit, but is also
    required for the shared heap write barrier. Unlike the generational barrier, the shared heap barrier can't be elided for map values.

Currently the Isolate is gotten off of the object that the operation is

incorrect as it shouldn't be used to run JS, nor does it have
HandleScopes open. Plumb the executing Isolate through.

The CL is a prerequisite for the shared cage. Instead of storing
state variables (is_incremental_marking_in_progress,
is_young_generation_enabled) in the cage metadata, the CL moves them to
HeapHandle. The HeapHandle pointer is now retrieved from page-headers.

To make sure that the write-barrier code is better optimized, the
HeapHandle definition is moved to internal/ headers. The part of
BasePage that contains HeapBase (i.e. HeapHandle) pointer is also
extracted and moved to the headers.

We previously missed out on turning ConsString objects into ThinStrings
due to the flattening step in StringTable::LookupString.

  // Example input string:
  string = cons("A", cons"B", "C"))
  // After flatten:
  string == cons("ABC", "")
  // OLD: After internalising and thinning:

The new behaviour yields a thin string after internalising:

  // NEW: After internalising and thinning:

If enabled, a signal handler is installed which intercepts memory access
violations (e.g. SIGSEGV) and checks whether they occurred inside the
sandbox address space, in which case the process is terminated cleanly
as this does not represent a (security) issue with the sandbox. However,
if the access violation occurred outside the sandbox, the access
violation is forwarded to the original signal handler.

The filter can be enabled in d8 by specifying
--enable-sandbox-crash-filter.
