Request for review (S): 6817525: turn on method handle functionality by default for JSR 292

[John Rose]

EnableInvokeDynamic and related switches may be useful for diagnostic testing, for root cause analysis.  And they are needed to differentiate behavior of 1.6 from 1.7.  But they are probably not useful as full product switches.  Unless there's a reason against it, we should categorize them as diagnostic switches.  This will affect the messages in methodHandles.cpp as well as the defs in globals.hpp.

Also, in arguments.cpp, I suggest replacing "supported since 1.7" by "not supported before 1.7", which is logically more precise.

Thanks!
