Version 3.1.1
Perform security checks before fetching the value in Object.getOwnPropertyDescriptor.
Fixed a bug in Array.prototype.splice triggered by passing no arguments.
Fixed bugs in -0 in arithmetic and in Math.pow.
Fixed bugs in the register allocator and in switching from optimized to unoptimized code.
