A tiny contribution for the IWYU day: Include allocation.h in every
header which uses BASE_EMBEDDED and/or AllStatic. Note that still only
45 out of 135 headers in src/ can be used stand-alone, but at least
this is a little bit more than before...

CPU profiler: sample call stack on profiling start.
This simplifies writing tests a lot, because it is now possible
to guarantee that certain function will present in a profile by
starting profiler from inside it.

CPU profiler: make code events handling scalable.
I changed the implementation of a queue between the VM and processor
thread to be unbounded and lock-free, using Herb Sutter's example from
DDJ article: http://www.ddj.com/high-performance-computing/210604448
This had brought back profiling overhead to a minimum for the page
from Chromium's issue 16184.
