  clang/HIP: Do not call ocml in scalbln implementations (#129639)

I do not understand why this was calling the float version with
an implicit cast from the long. Just clamp to the bounds of int,
and use the generic ldexp (this is also how musl does it, except
scalbnf is the base implementation there).

Somehow INT_MIN was also not defined, so deal with that.
