RFR(S): 8061250: serviceability/dcmd/compiler/CompilerQueueTest.java failed

[Nils Eliasson]

Hi,

Please review this change.

There was a small difference in logging depending on whether tiered was 
on or off. This made the parsing in the test fail. This problem was not 
caught earlier by a few reasons:

1) We don't run the testing with a client VM very often
2) Running server with tiered off don't compile much and the queue is 
mostly empty
3) When runnning with Xcomp compilation is synchronous so the queue is 
always empty

The change includes a small fix for consistent logging indentation 
regardless of tiering, and adding a non-tiered test-case.
