For now I will restrict the solution to 64 bit and 32 bit floats. Making nextUp/nextDown work for extended precision reals in CTFE is difficult because some D compilers interally use 64 bit precision for CTFE real calculations even though the target has extended precision reals. This specifically happens in the FreeBSD_32 and FreeBSD_64_64 tests in the CI suite.
