RFR(XS): 8072844: Use more efficient LambdaForm type representation

[Michael Haupt]

Dear all,

thank you, Claes, Sundar, and Ulf - here's a new webrev: http://cr.openjdk.java.net/~mhaupt/8072844/webrev.01

The string signature is now only used in tracing and assertions, which is why caching it is not necessary.

Caching the method type might be worthwhile, but this requires further analysis: it is used in LF bytecode generation and DMH creation only. I'll keep it out of this change but bear it in mind.

Thanks,

Michael
