`scalbn` is supposed to compute more efficiently than directly performing x*FLT_RADIX^n as described in C99 Standard (in existing implementations, it doesn't necessary holds).

A rough compare has been performed locally by fixing `n` and test over the range defined in the existing infra for `scalbnf(x, n)`:
