Many safepoint tables do not contain any deoptimization info and/or no
callee-saved registers. Do not emit empty fields for all entries in this
case.
This often shrinks the size of the encoded safepoint table by more than
50%.

Drive-by cleanups:
- Rename fields of the safepoint table entries to clarify their meaning
("tagged slots" instead of "bits", "tagged register indexes" instead of
 "register bits").
- Include the PC in the decoded {SafepointEntry} to make it the single
source of truth.

This is a reland of 90a9d6cb

The original CL got reverted because of two different issues:

* The DCHECK failure on AllowGarbageCollection::IsAllowed() got fixed
  in https://crrev.com/c/3289625.
* The crash with the incremental marking job were because of a nested
  GC started from a SafepointScope. This CL adds IgnoreLocalGCRequests
  scopes to SafepointScopes in src/heap.

In addition this CL prevents shared GCs during isolate deserialization
by locking the clients_mutex_ until the isolate is fully deserialized.
The original GC used a DisallowSafepoints scope to prevent shared GCs
from interrupting isolate deserialization.

Original change's description:
> [heap] Support multiple clients in shared GC
>
> Add support for safepointing multiple isolates as described in the
> design doc (link is below). A safepoint across multiple isolates is
> considered a global safepoint to distinguish it from regular safepoints.
>
> The basic idea behind the implementation is that we reach a
> safepoint for each client. What's new is that now also main threads
> need to participate in the safepointing protocol and need to give up
> control in time. The slow paths of Park(), Unpark() and Safepoint() on
> the main thread need to be adjusted for this reason as well.
>
> This CL introduces GlobalSafepoint and GlobalSafepointScope to mirror
> IsolateSafepoint and IsolateSafepointScope.
>
> This CL adds the type IgnoreLocalGCRequests, it is used to prevent
> Park() and Unpark() from honoring the request from background threads
> to perform a local GC. This is used heap-internally to not have GCs
> (or even nested GCs) in certain locations. E.g. when initiating a
> safepoint to perform a GC we don't want a "recursive" GC to occur.

Starting an incremental GC when it is not supported is not allowed but
trying to finalize one when it might be unknown whether it's supported
or not should be legal.
In such cases, finalization would immediately bail out since there is no
active gc.

explicitly allow this here in order to use SafepointScope.
