Delete branch "fix-mulsf3-exponent"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Originally reported by @Panda381. I thought this case was unreachable for multiply, but it's unfortunately just rare. This costs one cycle.
Ah, this needs to also check overflow after exponent adjustment. I'll add another testcase
...and do that without making underflow slower. Ready for review now
