RFR (S): 8024087: Remove dead JVM_{Get, Set}PrimitiveFieldValues functions

[Mikael Vidstedt]

Coleen/Christian/Chris/Dmitry - Thanks for the reviews.

Since this is only relevant on pre-1.4 JDKs I actually really think 
nobody depends on this.

I noticed that I needed one small additional change in nativeLookup.cpp 
- the struct is iterated over in the function just below 
(lookup_special_native) and the start index was previously initialized 
to 2 for jdk1.4+, skipping the first two entries in the array. With that 
change in place everything works as expected.

I uploaded a webrev with that change included for the curious:

Cheers,
Mikael

These functions were used back in JDK 1.3.1 to intrinsify two java.io.Object{Input,Output}Stream methods, but the Java code was rewritten in the JDK 1.4 time frame and the corresponding Java methods are no longer there, meaning this code is well and truly dead and has been so for many years.
