[drlvm][jit] ineffective access to class type literals
------------------------------------------------------

                 Key: HARMONY-5856
                 URL: https://issues.apache.org/jira/browse/HARMONY-5856
             Project: Harmony
          Issue Type: Improvement
          Components: DRLVM
    Affects Versions: 5.0M7
            Reporter: Alexey Varlamov
         Attachments: ClassLiteralBench.java

Jitrino.OPT compiler does not provide fastpath loading of class literals (as opposed to string
literals and final fields).
Use the attached microbenchmark to verify:

working_vm>java ClassLiteralBench
class literal time=150 sum=849786080
string literal time=130 sum=1570286080
final field time=150 sum=-1468617312

working_vm>deploy\jdk\jre\bin\java.exe -Xem:server ClassLiteralBench
class literal time=3155 sum=1471484416
string literal time=480 sum=-2102982880
final field time=761 sum=738006112
