Port the eager deopt handling in the use marker and register allocator
to do the same thing with lazy deopts. This requires moving the lazy
deopt info to be a pseudo-input before the node, same as eager deopt
info, so that the regalloc can read it without needing the Node's
opcode.

For now, this means that a node cannot both eager- and lazy-deopt; if we
need this in the future we can rethink it.

Since the code is generated unconditionally, using a DCHECK to check
that shared RO heap is enabled breaks builds with
v8_enable_shared_ro_heap set to false, this patch turns that into a
CSA_DCHECK so it only crashes when V8 actually attempts to store into
a shared struct while the RO heap isn't shared at run time.

This changes the logic for generating method names in `error.stack` to
prepend an inferred type name only when the function name is a valid
ECMAScript identifiers and does not equal the inferred type name, to

(1) give developers more control over the exact name shown in
    `error.stack`, as well as
(2) avoid confusion in the presence of renaming of local variables.

Previously we'd leave the function name as-is if it was prefixed by the
inferred type name, but that condition is unnecessarily strict, and led
to a bunch of inconsistencies around special names like
`<instance_member_initializer>` where this dynamic approached often
prefixed it with the correct type name, but also sometimes got it wrong
and prepended `Object.`, which is very unfortunate and misleading.
Specifically for these special names, we'll add logic later in the
parser to infer a useful (complete) name.

The design doc (https://bit.ly/devtools-method-names-in-stack-traces)
contains more background and examples of why we do this change.

This is a reland of commit 3ce690ee

Changed for the reland:
- Remove the currently-unused BytecodeArray member to avoid MSAN
  failures.
- s/return/continue/ in optimizing-compile-dispatcher.

Original change's description:
> [osr] Basic support for concurrent OSR
>
> This CL adds basic support behind --concurrent-osr,
> disabled by default.
>
> When enabled:
> 1) the first OSR request starts a concurrent OSR compile job.
> 2) on completion, the code object is inserted into the OSR cache.
> 3) the next OSR request picks up the cached code (assuming the request
>    came from the same JumpLoop bytecode).
>
> We add a new osr optimization marker on the feedback vector to
> track whether an OSR compile is currently in progress.
>
> One fundamental issue remains: step 3) above is not guaranteed to
> hit the same JumpLoop, and a mismatch means the OSR'd code cannot
> be installed. This will be addressed in a followup by targeting
> specific bytecode offsets for the install request.
>
> This change is based on fanchen.kong@intel.com's earlier
> change crrev.com/c/3369361, thank you!

Adds concurrent marking for reaching through v8::TracedReference.
Before this CL, a v8::TracedReference would always be processed on the
main thread by pushing a callback for each encountered reference.

This CL now wires up concurrent handling for such references. In particular:
- Global handles are already marked as well and not repurposed during
  the same GC cycle.
- Since global handles are not repurposed, it is enough to
  double-deref to the V8 object, checking for possible null pointers.
- The bitmap for global handle flags is mostly non-atomic, with the
  markbit being the exception.
- Finally, all state is wired up in CppHeap. Concurrent markers keep
  their own local worklist while the mutator marker directly pushes to
  the worklist owned by V8.

Make LazyDeoptInfo and EagerDeoptInfo both store a
CheckpointedInterpreterState for the bytecode position and
