Hi all,

Please review patch:

Problem:
the test changes 'TypeProfileLevel' via WhiteBox during execution, but 
'TypeProfileLevel' isn't supposed to be changed and there's the asserts 
based on that. the test w/ '-Xcomp and -XX:-TieredCompilation' triggers 
one of these asserts.

Fix:
- as a flag to change, the test uses 'VerifyGCStartAt' instead of 
'TypeProfileLevel'. 'VerifyGCStartAt' is safe to change during execution
- removed 'System.out.println' which was left by accident

testing: failing tests locally w/ different flags combinations
