7d478d9621 Revert of Remove obsolete V8_INFINITY macro. (patchset #3 id:40001 of https://codereview.chromium.org/798413003/) 
Reason for revert:
Speculative revert. This seems to block the current roll: https://codereview.chromium.org/819653003/

I retried several times, also with a new roll. The error is internal - but that doesn't make much of a difference.

a4506cd3f2 Move platform abstraction to base library 
Also split v8-core independent methods from checks.h to base/logging.h and
merge v8checks with the rest of checks.

The CPU::FlushICache method is moved to CpuFeatures::FlushICache

RoundUp and related methods are moved to base/macros.h

Remove all layering violations from src/libplatform

5a564648dd Improve reproducibility of test runs. 
Add random seed to run-tests.py, using either a user supplied
value or a random number generated by random.SystemRandom().
This same random seed is passed to all test cases, making sure
that we can easily reproduce test failures that depend on
random numbers (i.e. bugs related to our handwritten ASLR).

Also fix all uses of rand() to make use of our RNG class
instead.

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.

1193987313 Fix double-rounding in strtod. 
Don't use floating-point operations on Linux,x86 to compute strtod. Since the
floating-point stack on Linux is set to 80bit double rounding may occure.

When falling back to gay_strtod append several '0's so that Gay doesn't take
the same shortcut either.

Windows' strtod doesn't correctly read 3e-324 a the lowest denormal, but returns 0.0 instead.
Using 4e-324 is still the same value and works.
