* CPU functions now exist in Hardware::CPU * Added compatibility functions in compat/hardware_compat.rb * Names are less specific to Mac hardware, e.g. CPU.family instead of Hardware.intel_family * Hardware::CPU.family works for both Intel and PowerPC * New helper methods on CPU, like .sse4? and .altivec?
