0571adf189 [compiler] Remove frame state combine pushing
With FCG no longer able to deoptimize, we can remove the "push" version
of output frame state combine, as deoptimisation to bytecode is always
the PokeAt variant.

3bef2af6ef [build] Set MSVS .obj folders in gyp for v8_base
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.

89154bf681 Revert "[wasm] Run foreground compilation tasks as normal tasks"
This reverts commit 1520a8518a.

Reason for revert: This CL does not do what it should. All tasks which access the isolate have to be cancelable to guarantee that the isolate still exists when the task is executed. Foreground compilation tasks access the isolate, so they cannot be just normal tasks.

This CL adds a new function {InitializeCompilationUnit} to initialize
a single compilation unit and not just all compilation units at once.
This is necessary for streaming compilation eventually. This also
required some refactoring on how the working queue for compilation units
works. Previously the synchronization was done with an atomic counter,

all work is done. I plan to change this in a different CL.

Since the code would not be tested without streaming compilation, I added

937b5011b8 [parser] Skipping inner funcs: Associate data to SharedFunctionInfo, not Script.
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".

1520a8518a [wasm] Run foreground compilation tasks as normal tasks
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.

fd24deb0b2 [turbofan] Replace uninitialized JSConstruct nodes with SOFT deopt.
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.

1c555714db [turbofan] Further optimize spread/apply with arguments/rest parameters.
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
event emitter.

347e6215c5 Fix HasOwnProperty stub for interceptors
When internalization of the key fails because the string does not
exist in the StringTable yet, then no regular object can possibly
have a property with that name, so just returning "false" is safe.
However, for objects with interceptors this is not true, as there
may well be intercepted properties whose keys have not been
internalized. So "special API objects" must take the slow path to
query any interceptors.

d6aed4435f [wasm] Use pending exceptions consistently
In our internal code, we should only use pending exceptions. They will
be converted to scheduled exceptions on the API boundary.
Hence, the ErrorThrower just sets a pending exception; it should never
have to think about scheduled exceptions. The new
ScheduledErrorThrower inherits from ErrorThrower and reschedules any
pending exceptions in its destructor (turning them into scheduled
exceptions).
In some situations, there might already be a scheduled exception, e.g.
when calling other API methods (v8::Value::Get). In this case, the
ErrorThrower should also not set another pending exception. For the
reasons mentioned above, this can only be handled in the
ScheduledErrorThrower, which is used the API methods.

This fixes one DCHECK failure and one TODO about scheduled exceptions
if no instance can be created, because the start function throws.

9845f01a34 [compiler] Remove OSR code cache
There are very few cases where OSR code can be re-used, and where the
function won't be non-concurrently optimized after OSR has happened.
Maintaining the OSR code cache is unnecessary complexity, and caching
OSR prevents us from e.g. seeding the optimizer with the actual OSR
values.

So, this patch removes it.
