5494920a18 [turbofan] Use frame state before for shift operations as well.
This was already done for other binary operations, so it's basically
copying the existing functionality to shift left and shift right
logical/arithmetic.

36b4a498d6 Prevent stack overflow in the serializer/deserializer.
We keep an eye on the recursion depth. Once it exceeds a limit, we serialize
only the object header and size, but defer serializing the object body for
after we have unwound the stack.

2111d18dba [turbofan] Add frame state before JavaScript comparisons.
Use these check points to optimize comparisons where we already know
that one side cannot be a String (or turn into a string via
ToPrimitive).

Also remove bunch of useless DoNotCrash tests for the scheduler that are
painful to maintain and add almost no value.

cf07add227 Don't create debug context if debug listener is not set
If there had been no debug listener v8::Debug::GetDebugContext would have created new context and wouln't have kept reference to it. This way we may well end up with several debug contexts and disabled debugger.

As a side effect this change allows to efficiently distinguish debug context from blink contexts by simply comparing handles.

1ebbaaa036 Factor out core of Array.forEach and .every, for use in TypedArrays
The idea is to make this the model for future TypedArray methods.
A possible downside could be lower array method performance
if everything gets polymorhpic (but if enough inlining happens, it
should still be fast), but on the upside, this change means that
the TypedArray methods won't create as much code size bloat.

bd56d279b6 Resolve references to "this" the same way as normal variables
Make the parser handle references to "this" as unresolved variables, so the
same logic as for the rest of function parameters is used for the receiver.
Minor additions to the code generation handle copying the receiver to the
context, along with the rest of the function parameters.

- Fix the ugly hack that passes the first stub parameter as the "this"

A few smaller changes were necessary to avoid failures in

would be retained by being context allocated, leading to test failure.

methods, rather than a version for each TypedArray type. This

This introduces V8.MemoryHeapCommitted and V8.MemoryHeapUsed histograms.

In contrast to the existing memory histograms, the new histograms are uniform in time, i.e. their samples happen at regular time intervals. The --histogram-interval specifies the length of the interval.

We implement this by linearly interpolating memory stats between GC and idle notification events.
