RFR 8224137: Analyze and port invocation tests to jtreg and co-locate to jdk repo

[Harold Seigel]

Hi,

Please review this JDK-14 change to move the invocation tests written by 
Vladimir Ivanov into the JDK repo and make them runnable using JTReg.

This webrev adds three tests, invokeinterfaceTests.java, 
invokespecialTests.java, and invokevirtualTests.java.  Each tests run 
its set of sub-tests twice, once using class file version 51 and once 
using the current class file version.

Open Webrev: http://cr.openjdk.java.net/~hseigel/bug_8224137/webrev/

JBS Bug: https://bugs.openjdk.java.net/browse/JDK-8224137

The tests were tested on Linux-x64, Solaris, Windows, and Mac OS X.

The original tests can be found attached to JDK-8163974 
<https://bugs.openjdk.java.net/browse/JDK-8163974>. Besides the changes 
needed for JTReg and adding copyrights, I made the following additional 
changes.

 1. The tests now use the JDK's asm support instead of providing its own
    asm libraries.
 2. Only sub-test failures are written to the .jtr files.  Writing all
    sub-test results caused JTReg to truncate the output.
 3. Changed src/invokeinterface/Checker.java to skip private methods
    when looking for an overloading method.

The tests contain "TODO" comments and other thing needing clean-up.  
These will be addressed in a future RFE.

I put the tests into hs-tier3 because the invokeInterfaceTests.java test 
can run for up to 10 minutes (on Mac).  The other two tests take only 
1-2 minutes.  Is there a better tier for these tests?

Thanks, Harold
