Part 1: All synth functions that produce signed short.
That is:
- synth_1to1 with cpu-specific variants (synth_1to1_i386, synth_1to1_i586 ...)
- synth_1to1_mono and synth_1to1_mono2stereo; which use fr->synths.plain[r_1to1][f_16].
- synth_1to1_mono and synth_1to1_m2s; which use fr->synths.plain[r_1to1][f_16].
Nearly every decoder variant has it's own synth_1to1, while the mono conversion is shared.
