JDK-8034775 makes impossible to create VM w/ enabled tiered compilation and CICompilerCount explicitly set to 1:
CICompilerCount of 1 is invalid; must be at least 2
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Problem: - ciReplay/* tests can't create VM Root cause: - the tests specified '-XX:CICompilerCount=1', but after 8034775 it's impossible to specify '-XX:CICompilerCount=1' w/ enabled TieredCompilation. Fix: - CICompilerCount=1 replaced by CICompilerCount=2
