`IsHoleyElementsKind` doesn’t just check for holeyness — it checks for
dictionary elements as well. Its name should reflect that.

This patch renames `IsHoleyElementsKind` to
`IsHoleyOrDictionaryElementsKind`, which makes it possible to rename
`IsFastHoleyElementsKind` to `IsHoleyElementsKind` in a future patch.

Replace the second level visitation with a much simpler logic that
just separately dispatches the special cases. All other cases can
use a dispatch that just evacuates an object based on size.

This is similar to the logic used in the mark-compact collector. The
goal is to align behaviors as much as possible, highlighting and 
fixing performance issues in the different behaviors.

This CL is mechanical as possible. A followup will clean
up the naming scheme and dispatching.

The `FAST_` prefix doesn’t make much sense — they’re all just different cases
with their own optimizations. Packedness being implicit (e.g. `FAST_ELEMENTS`
vs. `FAST_HOLEY_ELEMENTS`) is not ideal, either.

This patch renames the FAST elements kinds as follows:

- e.g. FAST_ELEMENTS => PACKED_ELEMENTS
- e.g. FAST_HOLEY_ELEMENTS => HOLEY_ELEMENTS

The following exceptions are left intact, for lack of a better name:

- FAST_SLOPPY_ARGUMENTS_ELEMENTS
- SLOW_SLOPPY_ARGUMENTS_ELEMENTS
- FAST_STRING_WRAPPER_ELEMENTS
- SLOW_STRING_WRAPPER_ELEMENTS

This makes it easier to reason about elements kinds, and less confusing to
explain how they’re used.

Catch prediction for optimized frames had two issues:

Inlined frames were iterated from caller-to-callee (which could
result in incorrect predictions if one frame predicted CAUGHT and
another predicted PROMISE).

When encountering a builtin frame, we'd unconditionally return its
prediction (which is wrong if it predicted UNCAUGHT and another inlined
frame predicted either CAUGHT or PROMISE).

This CL fixes both issues and refactors the function to reduce nesting.

V8's catch prediction mechanism tries to predict whether a thrown
exception will be caught, just by looking at the current call stack.

At the time when catch prediction was first introduced, only a few
builtins (mostly related to Promise and Generator) could end up being
fed into the catch prediction mechanism. This is no longer the case now
that builtins are used in new ways, e.g. Array.p.forEach's continuation
builtins.

This CL removes the need to explicitly mark all builtins visible to the
StackFrameIterator as CAUGHT/UNCAUGHT/PROMISE, and instead defaults to
treating unmarked builtins as UNCAUGHT.

Building on Windows with gyp fails depending on the result from
sharding the src/v8.gyp:v8_base target. If two source files with the
same name are in the same shard, their output object file path would
conflict with one another. One example of this conflict is v8_base's
runtime/runtime.cc and the V8 inspector's protocol/Runtime.cpp that
is generated at build time, for which the files runtime.obj and
Runtime.obj would be created, but MSVS overwrites one of them with
the other.

Dividing the .obj output path by the original source's extension
prevents this overwrite.

This way, each lazy function needs to handle only the data relevant to
itself. This reduced data handling overheads.

Other changes:

1) Don't deserialize the data; once it's on the heap, it can stay there. Lazy
function compilation is only done in the main thread.

2) Separate ProducedPreParsedScopeData and ConsumedPreParsedScopeData. It's clearer, because:

- The data looks fundamentally different when we're producing it and when we're
  consuming it.

- Cleanly separates the operations we can do in the "producing phase" and in the
  "consuming phase".

This CL makes foreground compilation tasks normal (i.e. not cancelable)
again, because otherwise a deadlock can happen. I think the reason why
the foreground tasks were cancelable was to make sure that all tasks
either finish correctly or get canceled. However, since the isolate can
only shut down on the main thread, this means that the foreground task
should have already finished when the isolate shuts down, or it should
not have started at all. I reordered the deletion of the AsyncCompileJob
though to make sure that an AsyncCompileJob is removed from
CompilationManager before its promise is resolved.

Here is the deadlock: The JS code which is executed after a promise is
resolved is executed within the task which resolves the promise. In case
of async compilation this means that some JS code is executed within a
CompileTask. In JS, the shutdown of the isolate can be triggered. During
the shutdown of the isolate, the CancelableTaskManager waits for all
registered cancelable tasks to complete, including the CompileTask of
async compilation. This means that the CancelableTaskManager waits for
itself to finish, which is a deadlock.

Similar to JSCall, we can also replace uninitialized JSConstruct nodes
with SOFT deopts to ensure that we don't generate unnecessary dead code.
This for example shows up in the hot parts of the Node event emitter
currently where the generic code for handling events with 4 or more
parameters might not have been run, but we still generate most of the
code because the new Array call in the beginning is not turned into
a SOFT deopt immediately.

Drive-by-fix: Also refactor the BytecodeGraphBuilder's handling of
Construct bytecodes a bit to reduce the amount of code duplication.

Extend the use list check for the arguments object/rest parameters
during apply/spread optimization to allow for more cases, such that
even in code like

  function foo() {
    if (arguments.length === 1) return arguments[0];
    return bar.apply(this, arguments);
  }

we don't need to materialize the arguments object. This obviously comes
with a phase ordering problem, which we resolve by introducing a
waitlist in the JSCallReducer, which contains the nodes that we should
check again after all the other reductions are done, and which might
then be reducible. This is not 100% ideal, but get's us closer to where
we want to be, and it's crucial to speed up Node core, especially the

This CL replaces usages of utils.InstallFunctions and utils.InstallGetter()
with the DEFINE_METHOD* macros that ensure that the native function is
created in proper form from the beginning. Thus the function will not
require further reconfiguring like adding a computed name or removing of
'prototype' property.

improving function closures creation.
