Does anyone know of (or is there interest in creating) a library of basic,

What I'm thinking is something like Ardour's SSE-optimized mixing
subroutines... and updating it for later optimizations (SSE2, SSE3, ...).
Have you looked at liboil?

Specifically these functions:
gain: oil_scalarmultiply_f32_ns
mix: oil_add_f32
clip: oil_clip_f32
