As per WebAssembly Web API[1], the engine should only consider names
from the name section to synthesize function names in the context of
call stacks. We previously also added support to harvest the exports
table here in an attempt to improve the DevTools debugging experience,
but that needs a separate fix specifically for the inspector (which
should also take into account the imports to harvest names).

This change makes it possible to enable SharedArrayBuffer per Context,
controlling whether it should be enabled or not with a callback. The
previous implementation of the reverse origin trial for
SharedArrayBuffer was broken, since the feature could only be enabled
globally per process, and only if the feature flag is set early enough
in the v8 initialization. This does not play well with how origin
trials work.

The implementation is similar to the callbacks that already exist for
the origin trials for WebAssembly simd and exceptions.

SharedArrayBuffer is still controlled by the flag
harmony_sharedarraybuffer. If that flag is disabled, then
SharedArrayBuffer is disabled unconditionally. On top of that, this CL
introduces a new flag for enabling SharedArrayBuffer per context. If
that flag is set, a callback is used to determine whether
SharedArrayBuffer should be enabled.


Note that this only controls whether the SharedArrayBuffer constructor
should be exposed on the global object or not. It is always possible
to construct a SharedArrayBuffer using

  new WebAssembly.Memory({
    shared:true, initial:0, maximum:0 }).buffer.constructor;


There are few things which I do not like of this approach, but I did
not have better ideas:

1. The complex logic of dobule flag + callback. However, this seemed
the best way to me to not break embedders which rely on that flag
being enabled by default.

2. The fact that what actually matters is just whether the callback
returns `true` once. It would be good to check that the callback gives
a consistent return value, or to provide a better API that cannot be
missunderstood.

We potentially emitted the same gap move multiple times to satisfy slot
constraint of live ranges defined by a constant. Avoid this by keeping
track of already spilled ranges for a given instruction.

This is not expected to cause any regression because this case is rare.
If it does, a better approach to save allocations would be to re-use the
same vector by storing it somewhere that survives the function calls,
e.g. in the ConstraintBuilder.

Simplifies the traversal of nodes in Scheduler::PrepareUses to
avoid having to carefully order stack traversal for pre/post
ordering visits. Instead simply pre visit when pushing a node
onto the stack, then post visit the node when popping it from
the stack and then visiting it's inputs. This keeps the same
invariants required, but reduces visit overhead.

In addition, move checking for CoupledControlEdges out of
Increment/DecrementUnscheduledUseCounts such that the
coupled control edge calculation only needs to be done once
per node, rather than once for every input of the node. Also
remove unecessary recursion from these functions.

All told, these optimizations reduce the PrepareUses overhead
by 40-50%.
