RFR(M): 8171244: PPC64: Make interpreter's math entries consistent with C1 and C2 and support FMA

[Vladimir Kozlov]

Thank you, Martin

Looks good to me but someone familiar with ppc64 have to review it too.
I am fine with changes in abstractInterpreter.hpp. I will sponsor it since it need to go through JPRT.

Thanks,
Vladimir
