Version 2.5.1
Fixed bug causing spurious out of memory exceptions (issue http://crbug.com/54580).
Fixed compilation error on Solaris platform (issue 901).
Fixed error in strtod (string to floating point number conversion) due to glibc's use of 80-bit floats in the FPU on 32-bit linux.
Adjusted randomized allocations of executable memory to have 64k granularity (issue http://crbug.com/56036).
Supported profiling using kernel perf_events on linux. Added ll_prof script to tools and --ll-prof flag to V8.
