- "Fix typo."
- "Deuglify V8_INLINE and V8_NOINLINE."
- "Don't align size on allocation granularity for unaligned ReserveRegion calls."

Reasons for the revert are:
- Our mjsunit test suite slower by a factor of 5(!) in release mode.
- Flaky cctest/test-alloc/CodeRange on all architectures and platforms.
- Tankage of Sunspider by about 6% overall (unverified).

a797a35975 Refactor and cleanup VirtualMemory. 
Remove a lot of platform duplication, and simplify the virtual
memory implementation. Also improve readability by avoiding bool
parameters for executability (use a dedicated Executability type
instead).

Get rid of the Isolate::UncheckedCurrent() call in the platform
code, as part of the Isolate TLS cleanup.

Use a dedicated random number generator for the address
randomization, instead of messing with the per-isolate random
number generators.

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.

281de965a4 Import ConditionVariable class. 
Condition variables are synchronization primitives that can be used
to block one or more threads while waiting for condition to become
true.

Right now we have only semaphores, mutexes and atomic operations for
synchronization, which results in quite complex solutions where an
implementation using condition variables and mutexes would be straight
forward.

There's also a performance benefit to condition variables and mutexes
vs semaphores, especially on Windows, where semaphores are kernel
objects, while mutexes are implemented as fast critical sections,
it CAN be beneficial performance-wise to use condition variables
instead of semaphores.

b320dfcf58 Reland^2 "Add Chromium-style TimeDelta, Time and TimeTicks classes, and a new ElapsedTimer class." 
These classes are meant to replace OS::Ticks() and OS::TimeCurrentMillis(),
which are broken in several ways. The ElapsedTimer class implements a
stopwatch using TimeTicks::HighResNow() for high resolution, monotonic
timing.

Also fix the CpuProfile::GetStartTime() and CpuProfile::GetEndTime()
methods to actually return the time relative to the unix epoch as stated
in the documentation (previously that was relative to some arbitrary
point in time, i.e. boot time).

The previous Windows issues have been resolved, and we now use GetTickCount64()
on Windows Vista and later, falling back to timeGetTime() with rollover
protection for earlier Windows versions.

This also fixes the ARM CPU feature detection logic, which was

/proc/cpuinfo for CPU features.

f0305bd83e Instance-type-related fixes and cleanup. 
Things got quite a bit out of sync (don't we all love copy-n-paste?):

   * TypeToString didn't handle SLICED_STRING_TYPE,
     SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE,
     JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE.

   * INSTANCE_TYPE_LIST was missing entries for
     SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE.

To improve this maintenance nightmare a little bit, the missing
instance types were added to the INSTANCE_TYPE_LIST macro and this
list is now used via our beloved 2nd order macro technique in
TypeToString. As a side-effect, the strings returned by TypeToString
have a "_TYPE" suffix now, but this doesn't really matter and is a
small price to pay for consistency.

Removed INVALID_TYPE on the way, it had no real use.

707fdd4c6a Support idle time in CPU profiler 
This change provides an API for the embedder to tell CPU profiler if it is idle or busy with some task. This way we can discriminate between idle time and some native code execution.

e7585af65b Add flaky test classification feature to test suites. 
Test expectations can now include outcome: FLAKY.

The test runner can now run a class of tests (flaky|non-flaky|all). All tests are in the non-flaky class that are not marked as FLAKY.

The slash correction for windows is now pulled into the test name method. Currently the progress output on windows contains a mixture of / and \.

e9f6a2d7b4 Use first hit when dumping heap constants. 
This makes sure that the first hit is used when dumping heap constants
and hence "TheHoleValue" is not overwritten with other roots that are
initialized to the hole as well.

a0734ba3af Add deopt fuzzer tool. 
Can be run as a stand-alone script like run-tests.

Executes first all tests of a given test suite to collect the maximum number of possible deopt points. Runs then a fuzzing phase with artificial deoptimizations triggered during testing.

Works for now with mjsunit and ia32 only.
