Marc Tiehuis 8f1e417757 std/math: add ldexp and make scalbn an alias ...

We assume we are compiled on a base-2 radix floating point system. This
is a reasonable assumption. musl libc as an example also assumes this.

We implement scalbn as an alias for ldexp, since ldexp is defined as 2
regardless of the float radix. This is opposite to musl which defines
scalbn in terms of ldexp.

Closes #9799.
