Also replace the schoolbook algorithm with an optimized version

This also adds infrastructure to support interrupt checks from

This modernizes python code without breaking Py2 compat.
Ran with command:
futurize --stage1 -w predictable_wrapper.py
futurize --stage1 -w run-num-fuzzer.py
futurize --stage1 -w run-tests.py
futurize --stage1 -w v8_presubmit.py
This only adds the absolute import, which use these semantics. It
doesn't do anything differently in our case, these scripts are already
doing absolute imports. But with these changes, running `futurize
--stage2` will be less messy.

This skips gay-*.cc cctest files for lint checking. The files
contain 99.9% data not structures. Alternatively, maybe the
data could be moved to non-cc resource files.
This speeds up v8_presubmit without caching locally from 39s to 23s.
This is how it's executed on the continuous CI builder.

Cpplint usually checks for non-const reference arguments. They are
forbidden in the style guide, and v8 does not explicitly make an
exception here.
This CL re-enables that warning, and fixes all current violations by
adding an explicit "NOLINT(runtime/references)" comment. In follow-up
CLs, we should aim to remove as many of them as possible.

This enable test suites to check which test driver framework is used.
When using number fuzzer on mjsunit, we add a JS file that
switches off the optimization-state assertions.
Checking intrinsic state is not feasible on the number fuzzer and in
the past, we needed to skip tests on demand, which is a maintenance
burden. The main function of the fuzzer, to check for dcheck errors and
tsan issues, is retained.

This current fails, since {mmap} fails with EINVAL for empty mappings.
The destructor already has special handling for a {nullptr} mapping, so
we can just use {nullptr} for empty files. We get a similar error on
windows, and can fix it the same way.
On order to make presubmit checks happy, we have to skip copyright
checking and checking for terminating newlines for empty files.
