RFR (S): 8026047: add regression test for DisableExplicitGC flag

[Filipp Zhinkin]

Hi,

I've done following changes:
- misused @bug tag removed;
- VM options parsing refactored;
- append -XX:+PrintGCCause option to avoid the case when options contain 
-XX:-PrintGCCause;
- added method to ProcessTools that removes options that suppress VM 
output before creating ProcessBuilder.

Thanks,
Filipp.
