Reviewers: Yang,
Message:
PTAL whenever you have time (next year is fine).
Description:
Profiler improvements
(1) --prof-cpp: Collects ticks like --prof, but ignores code creation
events to
reduce distortion (so all JS ticks will be "unaccounted"). Useful for
profiling
C++ code.
(2) --timed-range flag for tick processor: Ignores ticks before the first
and
after the last call to Date.now(). Useful for focusing on the timed section
of a
test.
