lsr(-123, 0) not equiv. to -123 >>> 0

While converting a JS program to rescript I discovered that lsr(-123,0) is compiled to just -123 which is not equivalent to -123 >>> 0. I wonder if this is a bug?

i think these #7171 enhancements will fix what ever issue we are having here.

But i found an inconstency from OCaml Lib here.

-123 lsr 0 is giving output equivalent to -123 >> 0
where as
-123 lsr 1 is giving output equivalent to -123 >>> 1
