Rafael Espindola 06c6791742 When gvn decides to replace an instruction with another, we have to patch the ...

replacement to make it at least as generic as the instruction being replaced.
This includes:
* dropping nsw/nuw flags
* getting the least restrictive tbaa and fpmath metadata
* merging ranges

Fixes PR12979.
