From the log data generated with --log-function-events we can create a
detailed model of a function's lifetime. The parse processor displays
several stats at a given time (percent and count) on a per function or
byte basis:
- preparsing
- parsing
- eager/lazy compiling
- execution

Following CLs will move (and deduplicate) code from

We used to frequently break the ABI when we introduced new instance
types because some instance types are hard-coded in v8.h.
Now that we have more instance types available, we can leave some
room to anticipate future new instance types.
Also take this opportunity to reorder some instance types.

This moves the error-code check for verify-predictable mode to the API
method checking for status file outcomes, overwriting the default
behavior.
This is resembling the behavior prior to:
https://chromium-review.googlesource.com/c/808971/
Otherwise, the status file outcomes will expect some negative tests
to fail in the mozilla test suite, which pass in predictable mode.
Now, negative tests are simply not supported.

The new frame type is inteneded to represent native C++ stack frames.
JS code may sometimes make calls to helper native functions that do not
provide any special stack layout besides the return address and frame pointer.
Currently the stack iterator bails out when it sees an unknown frame.
The patch allows the iterator to unwind stacks having such frames.
