Comment (by jamal):
Don't rely on checksum to validate decoding of float data.
Core i7 950 is a Nehalem CPU. Core i7 3537U is an Ivy Bridge CPU.
The former supports only up to SSE4.2 instruction set, whereas the latter
supports AVX.
The aac and mp3 float decoders use a couple of functions that have AVX
implementations, which will give a different output than the non-AVX
counterparts (The ones used by the i7 950).
