The capacity may be modified on one thread when growing the table while
being used in a DCHECK (to sanity-check a provided
ExternalPointerHandle) on another thread, resulting in TSan failures.
This CL turns these accesses into atomic accesses and adds a comment
explaining when the capacity value can be used reliably.

```
EnsureHash();

which requires an additional load and might be misleading in the
presence of forwarding indices for shared strings, as raw_hash_field()
can return a forwarding index, whereas EnsureRawHash() will always

The existing version for paged spaces simply reset the freelist, which
doesn't work for tests that require actual objects in the space.
The version for new space also doesn't work because it assumes
everything after top is free space.

Fill the space with FixedArray by iterating over the freelist and
creating an object in place of each freelist entry.
This method actually fills the space, so that we can also use it to
force page promotion.

Worklist uses a singly-linked list of segments to hold entries.
Segment size was based on a compile-time constant but already stored
in the segment itself.

Rework the segments to query `malloc_usable_size()` on allocation and
adjust the capacity properly. For PartitionAlloc, it turns out that
there's ~20% more capacity available for the 64-element segments.

This slows down actual allocation of the segments with the upside of
improving utilization and requiring 20% less segments.

Instead of defining one global (FLAG_foo) per flag, define all flag
values as fields in a global {v8_flags} struct. This guarantees that the
memory is contiguous, and together with proper alignment allows us to
later memory-protect that memory space.

In order to avoid rewriting all existing code that uses the {FLAG_foo}
syntax, we define global aliases: {FLAG_foo} is a reference to
{v8_flags.foo}.

After the next branch cut (v10.6), follow-up CLs will rewrite all
existing code to use the {v8_flags.foo} syntax, and after another branch
cut (v10.7) the aliases will be removed.
This should allow us to merge back most fixes to the previous branch
(N-1). Merges to stable (N-2) might still require resolving merge
conflicts manually, if they modify code that reads flags.

Original Commit Message:

    StringConstantXXX were introduced when we switched to concurrent
    compilation, as a way to build strings in Turbofan in a background
    thread, without having to actually allocate them on the main heap
    from the background. See https://crrev.com/c/1221807.

    Now that we have local heaps, we can actually allocate strings from
    the background, making StringConstantXXX useless.

    Moreover, we would fold constant string concatenations into
    ConsString, which sounds a bit dubious for performance. Now, small
    constant string concatenations will be folded into SeqStrings, while
    larger ones will remain ConsString, just to avoid the quadratic
    worst-case.
