Push version 2.5.9 to trunk.
Fixed crashes during GC caused by partially initialize heap objects.
Fixed bug in process sample that caused memory leaks.
Improved performance on ARM by implementing missing stubs and inlining.
Improved heap profiler support.
Added separate seeding on Windows of the random number generator used internally by the compiler (issue 936).
Exposed API for getting the name of the function used to construct an object.
Fixed date parser to handle one and two digit millisecond values (issue 944).
Fixed number parsing to disallow space between sign and digits (issue 946).
