RFR: 8198888: Reduce string allocation churn in InvokerBytecodeGenerator

[Peter Levart]

Hi Claes,

  623             name = c.getName().replace('.', '/');

Did you know that there are 319 occurrences of .replace('.', '/') in JDK 
sources and tests (45 occurrences in java.base without tests)?

Isn't that enough to create a special API on the java.lang.Class that 
would cache this or at least something in an internal java.base package?

Regards, Peter
