There are many test names in the v8 code base that prefix
others, which makes it hard to only run those tests.

In particular, rename FormalParameterParsingState and friends to FormalParameters etc.

This should not change any logic, but is a preparatory CL for a bunch of follow-up fixes and clean-ups.

Using the GraphBuilder base class forces each node creation to go
through a virtual function dispatch just for the sake of saving the
duplication of the NewNode helper methods. In total that added up to
saving minus (sic!) six lines of code.

There is already non-throwing version FrameMirror.restart and RestartFrame in the livedit-debugger.js just adds a throwing wrapper around it.

Also NEEDS_STEP_IN_PROPERTY_NAME was removed, the client code can decide based on the stack_modified field if "step in" is required.

This preserves the context-independent entry in an optimized code map
across GCs when the code is considered young (i.e. less than 3 ages).
Note that any context-dependent entry for the same code will still be
flushed immediately when the respective context dies, hence context
lifetime is not increased.

This allows the optimized code map to contain no context-dependent
entries, but still hold one context-independent entry. This is a
precursor to extending the lifetime of the context-independent entry.

This fixes a recent regression where the register holding the original
receiver was pushed onto the stack before the internal frame within the
CallStubInRecordCallTarget helper was created. That in turn confused
the stack walker when allocations in these stubs failed.

This fixes a recent regression where the register usually holding the
original receiver was pushed onto the stack even when the stub was not
compiled for super calls (i.e. IsSuperConstructorCall). This led to
untagged values being present in the stack frame.

The background parser checks for debugger state in its constructor. This
is not good enough, since the debugger state may change afterwards, but
before compiling takes place. As the background parser can only parse
lazily, this could mean that due to debugging, we try to eagerly compile
an inner function we have not eagerly parsed.

Unit tests for the live range conflict detection mechanism (CoalescedLiveRanges) in the Greedy Allocator.

Consolidated conflict detection and traversal logic in CoalescedLiveRanges to avoid duplication in both code and testing. In addition, this change achieves better separation between CoalescedLiveRanges and other register allocator components, improving testability and maintainability.

The InterpreterAssembler needs to specify a specific CallDescriptor type
instead of using the SimplifiedCDescriptor type. This CL makes it possible
to specify the CallDescriptor used by the RawMachineAssembler instead of
specifying a MachineSignature.

at some point.

Revisit of https://codereview.chromium.org/910333004.

Use 4MB heap page size over the default of 1MB.

This change provides an improvement of 1.86% on the composite octane
benchmark score on PPC. This is 0.56% more than if --min_semi_space_size=4
was used to specify a 4MB heap page size.

Additionally, two more tests required modification to account for
configurable heap page size.
