On some branches of the search tree for a binary-search switch, the
input value is sufficiently constrained that we could unconditionally
jump to the last possible case rather than checking for value equality.
This shortens some builtins by a few instructions and might speed things
up, though I expect the effect to be small.

We probably expect a binary-search switch to take log(n) time in all
cases, but there is currently a possibility of that expectation being
broken. I'm not aware of any place where this actually happens, but if
the default handler immediately follows the switch dispatch block in
assembly order, then unconditional jump instructions for that handler
would be omitted. This omission could cause linear execution time, where
every case is checked before falling through to the default handler.

This change introduces a new function to emit an unconditional jump
instruction regardless of whether the target is the following block, and
uses that new function when generating a binary-search switch to ensure
consistently log(n) behavior.

This is a non-functional refactoring to make naming of stack traces more
consistent, and thus easier to reason about whether the "simple stack
trace" (stack trace API) or the "detailed stack trace" (inspector API)
is meant. Granted, these names aren't great by themselves, but at least
we should be consistent.

This also adds a new `Isolate::GetSimpleStackTrace()` and uses that
directly to implement the Wasm C-API, avoiding the roundtrip via the
`JSMessageObject`, which actually carries a detailed stack trace (which
by chance worked out so far).

This is the second step in the refactoring to make v8::StackFrame
more lightweight and usable for (long time storage) by the V8
inspector (see https://bit.ly/v8-stack-frame for an overview).

This is a purely mechanical change without any functional aspects.
The intention is to make the use case for the CallSiteInfo objects
clear, namely to serve as the backing store for the CallSite objects
exposed via the Error.prepareStackTrace() API and used under the
hood to implement the error.stack accessor.

This is a reland of 863bc2b8

Diff to original:
- Don't eliminate GC observable stores that were temporarily
  unobservable during traversal.
- Skip the previously added test for single-generation
- Add new test

Original change's description:
> [turbofan] Improve StoreStoreElimination
>
> Previously, StoreStoreElimination handled allocations as
> "can observe anything". This is pretty conservative and prohibits
> elimination of repeated double stores to the same field.
> With this CL allocations are changed to "observes initializing or
> transitioning stores".
> This way it is guaranteed that initializing stores to a freshly created
> object or stores that are part of a map transition are not eliminated
> before allocations (that can trigger GC), but allows elimination of
> non-initializing, non-transitioning, unobservable stores in the
> presence of allocations.

This is a reland of 2418d22a

Reland fixes:
  * Rebase this 2+ year old change 😱
  * Unpoison the kept segment before zapping it to make ASAN happy.
  * Carefully adjust allocation size tracking fields to compensate for
    kept segment.

This CL overrides the Summarize() method on the BuiltinExitFrame,
similar to what is already implemented on UnoptimizedFrame. This
way the stack trace capturing logic can be unified further, and
only needs to distinguish between JavaScript(ish) and WebAssembly
frames now.
