Add a feedback vector slot for computed property names in object
and class literals. Introduce new slot kind for storing
computed property names.
Change StaDataPropertyInLiteral to use the accumulator (again), so
we don't exceed Bytecodes::kMaxOperands.
We assume that most computed property names are
symbols. Therefore we should see performance
improvements, even if we deal with monomorphic ICs only.
This CL only collects feedback but does not use
it in Reduce() yet.

Currently the CompileLazy builtin checks the SFI expliciltly for FCG code. This means
if the SFI has bytecode we have to go through to the runtime to install the
interpreter entry trampoline into the JSFunction object.
Modify the builtin to always put the SFI code object into the JSFunction unless it's
the lazy compile stub on the SFI as well.

original commit message:
Don't fallback to the %StrictEqual / %Equal runtime functions for the
generic CompareIC slow path, but use the (new) StrictEqual and Equal
builtins instead. This avoids a performance cliff when mixing input
types for strict equality sites.

For benchmarks with multiple measurements (e.g. runtime, compile
time, generated code size), in case of error, we'd get only the
last portion of the name ("Compile"), which is ambiguous and makes
debugging dificult. This change includes the full name, e.g.
"Unity/Physics/Compile".

This moves the initialization of [[HomeObject]] for constructors from
the %DefineClass runtime function into the bytecode generator, and
makes it conditional (resolving an old TODO). As part of this refactor,
avoid a load of "prototype" by returning the class prototype from
%DefineClass.
This is one of many steps in moving more of class definition into
bytecode.

Remove a bunch of unnecessary v8:: prefixes in include/v8.h.
Some are still necessary for disambiguation purposes (e.g., between
bool Value() and v8::Value, or between v8::Isolate and
v8::internal::Isolate), but many aren't.

Recognize the special
NumberFloor(NumberDivide(lhs, rhs))
subgraph in TypedOptimization, where both lhs and rhs are in the
Unsigned32 range, and the result is a PlainNumber, and replace the
NumberFloor with a NumberToUint32 truncation.
This could be done in a cleaner way if we have a dedicated type for all
double values in the Unsigned32 range, but that would complicate the
type system quite a bit.

mjsunit/big-object-literal will exhaust the stack in debug builds,
due to different compiler settings. It will work in optdebug.
This disables for both. Adding an 'optdebug' test to .status files
is easy, but I don't want to contribute to the 'mode x variant explosion'.

These maps contain exactly the same information as the strict maps, so
this frees up a few pointers of native context space, gets rid of some
branches in FastNewClosure, and adds missing poisoned properties tests
for async functions.

The previous patch for this bug (https://codereview.chromium.org/2599793002/) was wrong because it changed the behavior of isCreatedPhi() in an incompatible way. The actual source of the bug is that escape analysis propagates information along cycles without considering the previous analysis value. This fix makes sure that if a previous merge cleared a field, then it stays cleared.

MarkCompactCollector::Prepare is too early in the rare case that we don't have a
marking deque yet. EnterFinalPause could then trigger
Heap::RegisterExternallyReferencedObject which rightfully fails because MC is
not properly set up.
Note that the DCHECK also triggers, without actual consequences, for aborting
incremental marking.
