Generate FMINNAN/FMINNUM/FMAXNAN/FMAXNUM from SDAGBuilder.
These only get generated if the target supports them. If one of the variants is not legal and the other is, and it is safe to do so, the other variant will be emitted.
For example on AArch32 (V8), we have scalar fminnm but not fmin.
Fix up a couple of tests while we're here - one now produces better code, and the other was just plain wrong to start with.
