  Log Message:
  -----------
  [WebAssembly] Use generic pseudo_fmin/pseudo_fmax opcodes (#208454)

The pmin/pmax instructions are equivalent to these with operands
swapped.

The existing matching code for these instructions was incorrect, because
it failed to handle signed zeros and NaNs properly. You can't treat
strict and non-strict comparisons the same in this context.
