RFR: 8315582: Exclude compiler/codecache/CodeCacheFullCountTest.java with Xcomp

[Leonid Mesnik]

Please review following fix which disable execution of compiler/codecache/CodeCacheFullCountTest.java  with -Xcomp.
Test fails because it is not enough to stat VM with Xcomp and other VM falgs. So just exclude it to reduce noise for now.
