There's a script for finding them (tools/check-unused-bailouts.sh), but make
sure you don't have an old .bailout-reason.h.swp or such around when using it...

This adds back the instanceof operator support in the backends and
introduces a @@hasInstance protector cell on the isolate that guards the
fast path for the InstanceOfStub. This way we recover the ~10%
regression on Octane EarleyBoyer in Crankshaft and greatly improve
TurboFan and Ignition performance of instanceof.

This change introduces a pipeline for the final stages of
bytecode generation.
The peephole optimizer is made distinct from the BytecodeArrayBuilder.
A new BytecodeArrayWriter is responsible for writing bytecode. It
also keeps track of the maximum register seen and offers a potentially
smaller frame size.

a runtime assert failure.

The new bytecodes replace two runtime functions. They are still unsupported by the bytecode graphbuilder, though.

The feature was deprecated in M49 and flagged off in M50.
This patch removes it entirely from the codebase.
