Updated V8 from git://github.com/v8/v8.git to 2215c442af2f0a4fce076e35ea061486d62778a1

Update V8 source to version 3.15.2

    * Performance and stability improvements on all platforms.
    * Avoid overdeep recursion in regexp where a guarded expression with a
      minimum repetition count is inside another quantifier.
    * Exposed last seen heap object id via v8 public api.
    * Implemented heap profiler memory usage reporting.
    * Preserved error message during finally block in try..finally.
    * Improved heuristics to keep objects in fast mode with inherited
      constructors.
    * Fixed lazy sweeping heuristics to prevent old-space expansion.
    * Fixed sharing of literal boilerplates for optimized code.
    * Expose more detailed memory statistics.
    * Cleaned up hardfp ABI detection for ARM (V8 issue 2140).
    * Report "hidden properties" in heap profiler for properties case.
    * Added optimizing compiler support for JavaScript getters.
    * Fixed computation of call targets on prototypes in Crankshaft.
    * Fixed ICs for slow objects with native accessor.
    * Fixed transcendental cache on ARM in optimized code (issue 2234).
    * New heap inspection tools: counters for object sizes and counts,
      histograms for external fragmentation.
    * Added more support for heap analysis.
    * Interpret negative hexadecimal literals as NaN. (issue 2240)
    * Improved API calls that return empty handles.
    * Added checks for interceptors to negative lookup code in Crankshaft.
    * Introduced global contexts to represent lexical global scope(s).
    * Allocate block-scoped global bindings to global context.
    * Add empty-handle checks to API functions (#ifdef ENABLE_EXTRA_CHECKS)
    * Check the return value of API calls on ia32 and x64.
    * Activated fixed ES5 readonly semantics by default.
    * Added validity checking to API functions and calls.
    * Switched on code compaction on incremental GCs.
    * ARM: allowed VFP3 instructions when hardfloat is enabled. (Chromium issue 152506)
    * Killed off the SCons based build. (relevant for testing)
    * Added a faster API for creating v8::Integer objects.
    * Speeded up function deoptimization by avoiding quadratic pass over optimized function list. (Chromium issue 155270)
    * ES6: Added support for size to Set and Map (issue 2395)
    * ES6: Added support for Set and Map clear method (issue 2400)
    * Made formatting error message side-effect-free.  (issue 2398)
    * Fixed V8 issues: 915, 1374, 1465, 1569, 1591, 1609 1645, 1804, 1914, 1981, 1991, 2016, 2017,
