RFR(M): 8054889 - Additional Compiler Diagnostic commands

[Nils Eliasson]

Hi,

This fix introduces three new diagnostic commands and corresponding 
tests. The commands are Compiler.queue for printing the contents of the 
compiler queue, Compiler.codelist for printing all nmethods in the 
codecache and Compiler.codecache for printing an informational code 
cache summary.
