  EmitCreateIteratorResult loads map from function's context

  Caching or serialization can cause full-codegen output to be shared
  between contexts. CreateIteratorResult, however, was doing the wrong
  thing by creating results with the map that was current when the code
  was generated. Instead, we should chase pointers to load the right map

The biggest change is the removal of the map wrapper objects:
we now operate directly on the observation weak map, since there
are already Get/GetOrCreate/Set functions for each info map.
Various other small cleanups as well, including the deletion of
unnecessary forwarding functions and making use of standard macros.

This is a reland of r24972, retaining GetObservationStateJS() to
keep snapshotting working properly.

The justification for doing this is to reduce the size of the graph and
therefore speedup later phases of compilation. The control reducer also
obviates the need to run the PhiReducer, since it subsumes it.

Scenario:
On reload, Devtools restores previously set break points. At this point,
since Devtools is already opened, all code is compiled with debug break
slots. No break points exist yet, so we would lazily compile inner
functions, even ones that cannot be compiled lazily without a context.
So when we use Debug::FindSharedFunctionInfoInScript to find the break
positions, those lazily compiled functions are skipped.

By eagerly compiling when debug is active, we make sure that whenever
Devtools is open, functions that cannot be compiled lazily without a
context are always compiled with its outer function.

The big change here is to split out each key type into its own
benchmark suite, since optimizations for different key types
are likely to be disjoint. ForEach tests have also been split
into separate "Iteration" suites, again with the thought that
iteration performance is likely separable from key type.

As part of adding the new tests, rejiggered the existing tests:
  - Map.set and Set.add (along with their Weak variants) no longer
    include construction costs in their scores
  - Moved key logic into the shared common.js
