flac dev - May 2014 - PATCH for fixed.c/fixed.h

Tests show that FLAC__fixed_compute_residual/FLAC__fixed_restore_signal
are slightly faster when flac_restrict modifier is added to their arguments.

(Encoding speed increase for flac -8 is about 2%. The difference is
not very big yet measurable).

Sorry, there was an error: encoding speed increase is about 0.5% for 32-bit
encoder and ~0% for 64-bit.

encoding speed increase is equal to 1.5-2% for 32-bit encoder compiled without
-msse2 option (I commented out this string in configure.ac to do some other
tests
and forgot to revert this change).

So, this patch makes little sense.
