[PATCH] D156538: [AArch64] Try to combine FMUL with FDIV

@dmgreen As you can see, `DAGCombiner::visitFDIV` does the conversion with `Options.UnsafeFPMath || Flags.hasAllowReciprocal()` so the patterns with `fmul` are not selected without the options.
In order to use only `fmul`, we could need to remove the `Options.UnsafeFPMath || Flags.hasAllowReciprocal()`. We could need to support patterns with both `fmul` and `fdiv` with different complex patterns. How do you think about it?
