Use === when possible instead of ==` about intervalarithmetic.jl HOT 4 CLOSED

today with @Kolaru we went through issues and closed the ones that seemed trivially completed / not relevant.

For this, iirc the reasoning was that it's unlikely to give and speed-up and prob not worth pursuing. Also note that === cannot be used with BigFloats

julia> a = big(1.0)
1.0

julia> b = big(1.0)
1.0

julia> a === b
false

if you would like to do more thoughtful benchmarks, feel free to reopen

This may be faster.

@lucaferranti Can you point out where was this completed? Or do you mean the implementation in the 1.0-dev branch (≛ and ==)? In any case, I'm not sure we use === in those functions...

Your explanation is fine for me; I was simply wondering because I didn't recall that we used it that way.
