If this has a visible impact on simulation speed, then we could build
a hand-optimized implementation of these packages as a .so lib, and
preload it before launching simulation... or, the generated simulator
could (with an option) load that optimized implementation itself?
gcc already generates good code for ieee packages, but that's not
enough. We could avoid recomputing bounds for these functions, as
they could be deduced at compile-time for most cases.
