We define a TestFailedError exception and raise it when we can reliably detect
that a test has crashed. All other exceptions are treated as infra failures and
are captured by the try-catch clause in MainWrapper function.
This also fixes all tests in run_perf_test.py, run_tests_test.py and makes sure
that both are run on any changes in tools directory.

This is a reland of
https://chromium-review.googlesource.com/c/v8/v8/+/1276468, without the
change "Also forces all non-trampoline RelocInfo ByteArrays for builtins
to be generated into RO_SPACE."
Creates a single RelocInfo to be used by all builtin trampolines and
stores it as a root. All trampolines then substitute this for their
trampoline at generation time with DCHECKs to make sure it is
identical.
On x64, this results in the OLD_SPACE part of the startup snapshot
decreasing in size from 165656 to 130808 (-34848) bytes and RO_SPACE
(in the read-only snapshot) increasing from 31248 to 31272 (+24) bytes.

(1) Fix "mksnapshot failure" detection to match the error message
that is generated when embedded builtins are enabled.
(2) Run "gn gen" whenever build.ninja is missing. This can happen
when out/<config>/args.gn exists already when gm.py is run for
the first time.

Originally timestamps were added in crrev.com/c/1159361 to ease debugging. Since
then, however, timestamps were introduce to the LogDog viewer and are rendered
in a separate column, making it easier to scan text for important messages
starting with '>>>'. We do keep the log level, but make sure that it always
takes a fixed width such that the actual messages are aligned vertically.

- add micro benchmarks for testing all the interesting slice cases
Also update a few assorted places in .tq code to make them more

The original version of this patch had an overly agressive assert that has
