JDK 9 RFR of JDK-8033416: Remove sun.misc.FpUtils

Back in JDK 5, the sun.misc.FpUtils class was added to provide low-level 
floating-point manipulations methods needed to write tests of the math 
library. Over time, those low-level functions have generally been added 
to the standard Java library and most of the methods in FpUtils have 
thus been deprecated.

Therefore, I think the start of JDK 9 is a good time to actually remove 
FpUtils from the platform; please review my change which does this:


The implementation of the ilogb and isUnordered methods was moved into 
the "Tests" helper class in the math library test directory.

(At the recommendation of Alan in the bug report, I verified that the fx 
jar files do not reference the FpUtils class.)
