  [CostModel] add basic handling for FP maximum/minimum intrinsics

This might be a regression for some ARM targets, but that should
be changed in the target-specific overrides.

There is apparently still no default lowering for these nodes,
so I am assuming these intrinsics are not in common use.
X86, PowerPC, and RISC-V for example, just crash given the most
basic IR.
