RFR(S): 8170767: Zero fastdebug build triggers assertion

[Severin Gehwolf]

Hi,

Could somebody please review this Zero only change? The problem was
there before, but only the fix for JDK-8169711 brought it to the
surface. The returned method kind for
java_lang_math_fmaD/java_lang_math_fmaF is no longer guarded by UseFMA
in abstractInterpreter.cpp

The fix is to generate stub entries for
java_lang_math_fmaD/java_lang_math_fmaF which were missing. Thoughts?

Thanks,
