RFR: 8164739: Remove computation of predefined interpreter forms

[Claes Redestad]

Hi,

LambdaForm predefines a number of forms for the benefit of the LF and
NF interpreters, which doesn't appear useful at all at this point.

JIRA: https://bugs.openjdk.java.net/browse/JDK-8164739
Webrev: http://cr.openjdk.java.net/~redestad/8164739/webrev.01/

Testing: all java/lang/invoke tests with various values for
-Djava.lang.invoke.MethodHandle.COMPILE_THRESHOLD to run with and
without LF interpretation.

Removing this code improves on previous work to improve indy
bootstrap to the point where the indy bootstrap happens in a few 
milliseconds, only loads 21 extra classes. On full program execution
there's no discernible time difference between the regular and the
MH variant.

Thanks!
