I don't think we need these implications. Features dependencies are already set in llvm/lib/Target/AArch64/AArch64.td

`def FeatureComplxNum : SubtargetFeature<
    "complxnum", "HasComplxNum", "true",
    "Enable v8.3-A Floating-point complex number support (FEAT_FCMA)",
    [FeatureNEON]>;`
   
`def FeatureJS : SubtargetFeature<

    "Enable v8.3-A JavaScript FP conversion instructions (FEAT_JSCVT)",
    [FeatureFPARMv8]>;`
