Previously the simplified operation `Number.min(x,y)` would lower to
`Select(Float64LessThan(x, y), x, y)` which would yield `y` when both
`x` and `y` are zeros, specifically when `x` was -0 and `y` was +0.
For `NumberMin` we need to use `Float64LessThanOrEqual` since we
generally allow -0 on the left hand side (in SimplifiedLowering).
