Side note: divsc3.c appears to be the only place in ``builtins`` where __compiler_rt_fmaxf is used.

What do you think - would it possible to move forward here ? (this would make things a bit more consistent across architectures / compilers).  Otherwise, I agree with the argument presented above "The behavior of signaling NaNs in Annex G is implementation-defined" (I missed it initially) - can abandon this PR.
