RFR(S) - JDK-8013875: Incorrect vtable index being set during methodHandle creation for static methods

[Bharadwaj Yadavalli]

Changes to address https://jbs.oracle.com/bugs/browse/JDK-8006267 
included modifications to methodHandles code.

John Rose pointed out that these changes are incorrect as static methods 
do not use vtable or itable indices. I made the necessary changes with 
his help.

Please review the changes.

Thanks,

Bharadwaj
