I believe the fmin_pseudo and fmax_pseudo instructions do this, but they are currently unimplemented for scalar types.

Nope, they are not the right instructions. They still propagate NaN.

This proposal feels a bit redundant - is there any architecture that has a 1:1 mapping to this operation? Otherwise it is straightforward to pattern-match the equivalent operation sequences if the default lowering is not good enough. E.g. the minimum operation for 32-bit inputs:

v2 = fcmp eq v0, v0
v3 = select.f32 v2, v0, v1
v4 = fmin_pseudo v3, v1
