[flac-dev] PATCH: asm versions for two _wide() functions

[lvqcl]

As I wrote earlier, GCC generates slow ia32 code for FLAC__lpc_compute_residual_from_qlp_coefficients_wide()
and FLAC__lpc_restore_signal_wide(). So 24-bit encoding/decoding is slower
for GCC compile than for MSVS or ICC compile.

I took FLAC__lpc_compute_residual_from_qlp_coefficients_asm_ia32
and FLAC__lpc_restore_signal_asm_ia32 asm functions and wrote their _wide
versions.
