Yingwei Zheng 3aae916ff7 Reland "[ValueTracking] Compute knownbits from known fp classes" (#92084) ...

This patch relands https://github.com/llvm/llvm-project/pull/86409.

I mistakenly thought that `Known.makeNegative()` clears the sign bit of
`Known.Zero`. This patch fixes the assertion failure by explicitly
clearing the sign bit.
