Add ASM function FLAC__lpc_compute_autocorrelation_asm_ia32_sse_lag_16.

Browse Source 
For the 32 bit x86 ASM functions there were already versions of this
function for lags (N = 4, 8, 12). They require lpc_order less than N.
The best compression preset (flac -8) uses lpc_order up to 12; it
means that during encoding FLAC also uses unaccelerated C function.
