RFR(M): 8213528: fp registers should not need to be saved around a CallLeafNoFP

[Roland Westrelin]

What Roman explains is right.

> And, please, file new RFE to remove NO_FP code.

I filed JDK-8213777 to clean the x86_32.ad file. So you want all parse
time code related to CallLeafNoFP to be removed?

Roland.
