Possible bug with operator overloading on traits/associated types

[jackmott]

See the following playground code:
https://play.rust-lang.org/?gist=bf70f00b6d1998921a4571bd331f6530

If you run it, it works. There are two bits commented out, a trait bounds for an Add<f32> and an
operator overload for Add<f32>. If you put those back in, you get an error trying to use the + operator.

It seems like the 2nd Add trait bound nullifies the first.

This occurs with 1.27stable and nightly as of this post. Ubuntu.

appears to be related to:
#24159 and #47897

[jackmott]

more info: whichever trait bounds appears last in the list on the trait, will work, the one before will not.

This now compiles.
