718a6a9a9e Revert r16648, r16641, r16638 and r16637. 
Original descriptions were:
- "Refactor and cleanup VirtualMemory."
- "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.

f6b7ec4da0 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.

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.

1083d1f817 Remove deprecated profiler API 
This change removes --prof-lazy command line flag that was introduced for the old CPU profiler implementation in Chrome DevTools. DevTools now use profiler API defined in v8-profiler.h

This change also removes methods for pausing resuming --prof profiler. These methods were deprecated in v.3.20 (https://code.google.com/p/v8/source/browse/branches/3.20/include/v8.h#4629)

After this change the profiler will always start if --prof option is passed and can be stopped either in the tests or if write to log file fails.

22b70b0508 Add OptimizedCodeEntry as a new heap object type. An optimized code entry represents an association between the native context, a function, optimized code, and the literals. Such associations are needed by the deoptimizer and optimized code cache to efficiently find related optimized code and functions for a given context or shared function info.

5857d951dd Fix definition of V8_*_C() macros. 
Make V8_INT64_C() and V8_UINT64_C() available in 32-bit mode as well,
so we can write readable constants (base 10) instead of having to
obfuscate them using V8_2PART_UINT64_C().
