This also threads through the parameter count and local count to the instruction selector. This will be later used to allow merging of various StateValues vector (and prepare for differential encoding which will not distinguish between parameters, locals and expression stack).

This API closely matches the Worker API. The differences:

1) The argument to the Worker constructor is a function to run, not a script.
2) Receiving a message from a worker is a synchronous API (as there is no event
loop).

The serialization done here is not robust as the real DOM implementation. For
example, recursive data structures or otherwise duplicated objects are not
allowed.

We resurrect the VectorSlotPair in order to be able to separate the
feedback input for the compiler from the actual type feedback vector
that is required to meet the IC requirements at runtime. This will allow
us to for example use feedback from a different context or divide the
type feedback vector into two separate vectors, without having to touch
the compiler. It'll allow use to load the vector from the shared
function info at runtime, while still consuming feedback in the
compiler (i.e. we don't rely on the feedback vector node to be a heap
constant).

This fixes a terrible interaction of code flushing and the clearing of
optimized code maps hanging off a SharedFunctionInfo. The following is
what happened:
1) Incremental marking cleared map in SharedFunctionInfo s, however it
   was not enqueued as a flushing candidate because one JSFunction f1
   still had optimized code.
2) Deoptimization of f1 made s eligible for code flushing.
3) Optimization of f2 added new entry to optimized code map of s.
4) The JSFunction f2 became unreachable and hence is never marked.
5) Incremental marking now visits f1, finds it eligible for flushing,
   also s is eligible for flushing, both are enqueued.
6) Marking finishes, code flusher clears f1 and s, but the optimized
   code map of s still contains an entry.
7) Boom!

This is another missing piece in the puzzle towards general inlining.
The fact that we can combine this with context specialization is a nice
