cf87e94c01 Move CompilationDependencies into compiler.
- Move the CompilationDependencies member of OptimizedCompilationInfo
  to Turbofan's PipelineData (and thus into the compiler namespace).
- Move compilation-dependencies.{cc,h} to the compiler directory.

4174a68e84 [wasm] Fix importing exported function in interpreter
When calling an import which is an exported wasm function, the
interpreter needs to look through the jump table to find the
actual code object.
We already had that logic for indirect calls, but it was missing for
imported calls.

cf88badcfe [turbofan] Add remaining DataView getters in TurboFan.
This CL implements Reduction and Lowering for the DataView Int32,
Uint32, Float32 and Float64 getters.

This makes DataView getters fully supported in TurboFan (except for
BigInts), and should bridge the performance gap with TypedArrays.

df41fa7a8a [wasm][fuzzer] Do not execute modules with start function
In the WebAssembly fuzzers we detect infinite loops with the
interpreter: if the interpreter does not finish after a finite number
of steps, we do not execute the compiled code. However, we cannot
redirect the start function to the interpreter in the fuzzer, and
therefore we cannot detect infinite loops in the start function. With
this CL we avoid the problem completely by not instantiating a module
in the fuzzer which has a start function. Note that the module still
gets compiled.

f8e76e4b97 [GetIsolate] Use RORoots for Oddball checks
Replace Is<oddball>(GetIsolate()) calls with a no-parameter version
that goes through ReadOnlyRoots, and add a version that takes a
ReadOnlyRoots if that is available in the parent (but Isolate isn't).

Also opportunistically clean up a few places where ReadOnlyRoots are
available but we still pass in an Isolate parameter.

59af0c3e91 [explicit isolates] Make read-only root Heap accessors private
Now that ReadOnlyRoots is used everywhere to access the read-only roots,
this makes the Heap accessors for such roots private.

It also adds tests that the roots reachable from ReadOnlyRoots are all
in RO_SPACE as well as tests that the roots still publicly accessible
from Heap are not in RO_SPACE. There's a white list in the file for
the few roots where the root pointer itself can change. (For instance
materialized_objects points to empty_fixed_array to start with before
before later pointing to a mutable array).

Also fixes up new use of heap->empty_fixed_array() in elements.cc added
since I cleaned it up.

> 2. map function literals from old source to new source,
> 3. create new script for new_source,
> 4. mark literals with changed code as changed, all others as unchanged,
> 5. check that for changed literals there are no:
>   - running generators in the heap,
>   - non droppable frames (e.g. running generator) above them on stack.
> 6. mark the bottom most frame with changed function as scheduled for
>    restart if any.
> 7. for unchanged functions:
>   - deoptimize,
>   - remove from cache,
>   - update source positions,
>   - move to new script,
>   - reset feedback information and preparsed scope information if any,
>   - replace any sfi in constant pool with changed one if any.
> 8. for changed functions:
