Introduce a RandonNumberGenerator class. Refactor the random/private_random uses in Isolate/Context.
...
The RandomNumberGenerator is a pseudorandom number generator
with 48-bit state. It is properly seeded using either
(1) the --random-seed if specified, or
(2) the entropy_source function if configured, or
(3) /dev/urandom if available, or
(4) falls back to Time and TimeTicks based seeding.
Each Isolate now contains a RandomNumberGenerator, which replaces
the previous private_random_seed.
Every native context still has its own random_seed. But this random
seed is now properly initialized during bootstrapping,
instead of on-demand initialization. This will allow us to cleanup
and speedup the HRandom implementation quite a lot (this is delayed
for a followup CL)!
Also stop messing with the system rand()/random(), which should
not be done from a library anyway! We probably re-seeded the
libc rand()/random() after the application (i.e. Chrome) already
seeded it (with better entropy than what we used).
Another followup CL will replace the use of the per-isolate
random number generator for the address randomization and
thereby get rid of the Isolate::UncheckedCurrent() usage in
the platform code.

HeapProfiler: very slow ~4min "take snapshot time" for 80MB gmail heap.
...
The reason of that is a number of cons strings in the app.
The app constructs a json string and as a result v8 heap has
a very long chain of cons strings.
Profiler counts all these strings as plain String objects and
assign the content of the strings as node names.
It required O(n^2) time and O(n^2) memory.
Solution: I introduced two new types, kConsString and kSliced string.
They do not use the content of the string for names. So the problem disappeared.
The heap profiler usability problem will be solved on Blink side.

Fix concurrent osr.
...
InstallOptimizedCode aquires ownership on the compilation info and deletes
it on return, tearing down the attached zone. The OptimizingCompiler
object is a zone object allocated in just that zone, so it also gets
deleted. Effectively, InstallOptimizedCode cleans up when it's done, so
the OptimizingCompiler object it receives is invalidated afterwards.

Use PAGE_NOACCESS for guard pages in Windows.
...
Up until now we used PAGE_GUARD for guard pages in Windows, which
will raise a STATUS_GUARD_PAGE_VIOLATION exception on first access
and grant regular access afterwards. This behavior is required to
implement automatic stack checking, or more generally to implement
applications that monitor the growth of large dynamic data structures.
However, this is not what we want for our guard pages, which are
used as a security mechanism. What we really want is PAGE_NOACCESS
here, which is the Windows-equivalent of PROT_NONE that we use on
all other platforms.
