Misc improvements to InnerClassLambdaMetafactory and InvokerBytecodeGenerator: - Define `ClassEntry` early, use it when profitable (there are some warts in the API where using `ce.name(), ce.type()` in a few places means we drop the link to the `ClassDesc` which will then be re-spun in later - should be revisited) - Use `mh.invokeBasic()` for zero-arg non-capturing lambda constructor calls(!) - Narrow name validation to the name passed in - We were calling `classDesc` twice per factoryType argument, refactored to reuse `argDescs`.
Interpreter instrumentation sees 1.5% less bytecode executed on netty startup tests, -2.5% on minimal lambda test.
