[9] RFR (L): 8059623: JEP-JDK-8043304: Test task: command line options tests

[Filipp Zhinkin]

Hi,

please take a look at CLI tests for segmented code cache (JDK-8059623).

There are three new tests:
compiler/codecache/cli/
   codeheapsize/TestCodeHeapSizeOptions
   printcodecache/TestPrintCodeCacheOption
   TestSegmentedCodeCacheOption

All tests consist of several test cases aimed to verify different aspects
of options' processing.

These tests partially overlapped with c/c/CheckSegmentedCodeCache test,
but add additional value - these tests actually check final values
of tested options and verifies PrintCodeCache output.

Bug id: https://bugs.openjdk.java.net/browse/JDK-8059623
Webrev: http://cr.openjdk.java.net/~fzhinkin/8059623/webrev.00/
Testing: manual & automated

This change depends on:
https://bugs.openjdk.java.net/browse/JDK-8054892: Improve compiler's CLI tests 
error reporting
https://bugs.openjdk.java.net/browse/JDK-8066440: Various changes in testlibrary 
for JDK-8059613

Thanks
Filipp.
