eb381b9444 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.

bbd26abedb Functions may not be optimized and we would like to know in cpu profiler what was the reason.
Current v8 implementation may disable optimization for a particular function or block it with help of dont_optimize flag.
The patch propagates the reason of that to the SharedFunctionInfo where cpu profiler can get it.

SharedFunctionInfo is a heap object so I extracted 8 bits from OptsCount for handling bailout reason code.

35490d82a9 Add OptimizedCodeList and DeoptimizedCodeList to native contexts. Both lists are weak. This makes it possible to find optimized code that is not referred to by any function, but still needs to be deoptimized. It obsoletes the weak deoptimizing code list in the deoptimizer data and generally simplifies the process of deoptimizing code.

7557ca80ba Add --trace-hydrogen-filter flag.
The flag restricts hydrogen.cfg output to functions passing the filter,
similar to what --hydrogen-filter does for optimization in general.

This is useful for investigating large repro cases where tracing all
functions would lead to an impractically large hydrogen.cfg file, but
restricting optimization using --hydrogen-filter is undesirable
(e.g. because it might cause the issue to no longer reproduce).

63defee477 First implementation of allocation elimination in Hydrogen.
This change implements a simple data-flow analysis pass over captured
objects to the existing escape analysis. It tracks the state of values
in the Hydrogen graph through CapturedObject marker instructions that
are used to construct an appropriate translation for the deoptimizer to
be able to materialize these objects again.

This can be considered a combination of scalar replacement of loads and
stores on captured objects and sinking of unused allocations.

9d9930ce99 Migrate instance of deprecated maps in HCheckMaps.
Currently only direct map checks are supported. Otherwise only polymorphic cases with a generic fallback behave properly, regular polymorphic cases still need to be adapted.

d2c443b774 Extract hardcoded error strings into a single place and replace them with enum.
I'd like to propagate bailout reason to cpu profiler.
So I need to save it into heap object SharedFunctionInfo.
But:
1) all bailout reason strings spread across all the sources.
2) they are native strings and if I convert them into String then I may have a performance issue.
3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer.

Also I think it would be nice to have error strings collected in one place.
In that case we will get additional benefits:

It allows us to keep this set of messages under control.
It gives us a chance to internationalize them.
It slightly reduces the binary footprint.

From the other hand the developers have to add new strings into that enum.

e53471dbaa Remove elements transitions from the transition array.
This is preparatory work for reordering the transition tree. Since elements transitions will be at the root of the transition tree, runtime access to them is slow since we have to walk the transition tree backwards first. Hence remove the optimization that promoted them to a special field, requiring a pointer (mostly NULL) in every non-simple transition array.
