cc21e58d30 [owners] Remove redundant OWNERS files in test/
We have a global test/OWNERS that has "file://COMMON_OWNERS".
This CL removes redundant OWNERS files in test/ subdirectories and
removes redundant entries from OWNERS files we need to keep for
special per-file entries.

878ccb33bd [cleanup] Avoid {Object::operator->}
This CL was generated by an automatic clang AST rewriter using this
matcher expression:

  callExpr(
    callee(
      cxxMethodDecl(
        hasName("operator->"),
        ofClass(isSameOrDerivedFrom("v8::internal::Object"))
      )
    ),
    argumentCountIs(1)
  )

The "->" at the expression location was then rewritten to ".".

1bc7124667 [roheap] Switch to ReadOnlyHeapIterator in mkgrokdump
HeapObjectIterator now has a DCHECK preventing iterating over read-only

instead.

9c06209306 Reland "[heap] Skip ro-space from heap iterators, add CombinedHeapIterator."
Code relocation info is now always allocated in old-space. Before relocation
info allocated for placeholders and builtins (which get replaced with
trampolines in nosnap builds) would become unreachable. Since read-only space
is not GCed and ReadOnlyHeapIterator doesn't check for reachability,
ValidateSnapshot would fail finding unreachable objects returned by
ReadOnlyHeapIterator.

Because trampoline relocation info gets replaced with canonical one, this only
affects no-embdded-builtins nosnap builds, which don't get much benefit from
read-only relocation info anyway.

A new check has been added to the read-only deserializer to verify that every
read-only object is reachable at mksnapshot-time.

The CombinedHeapIterator iteration order was changed to iterate over
read-only space first, because that's how HeapIterator worked.

This is a reland of 3d1d8eae77

> [heap] Skip ro-space from heap iterators, add CombinedHeapIterator.

> Read-only space sharing requires an iterator independent of heap. This

6cac1382f4 [cleanup] #include heap-inl.h less often
This takes heap-inl.h out of the "Giant Include Cluster".
Naturally, that means adding a bunch of explicit includes
in a bunch of places that relied on transitively including
them before.
As of this patch, no header file outside src/heap/ includes
heap-inl.h.

e0c3f6d6ca Disable embedded builtins
Embedded builtins have been regressing benchmarks incrementally as
more and more builtins were moved to the embedded blob. This has made
recognition and analysis of other possible performance issues more
difficult.

Let's disable embedded builtins until their performance is at an
acceptable level.
