Additionally, make use of this version to implement `ceil` and `ceilf`.
Musl's `ceilf` algorithm seems to work better for all versions of the
functions. Testing with a generic version of musl's `ceil` routine
showed the following regressions:
icount::icount_bench_ceil_group::icount_bench_ceil logspace:setup_ceil()
