Description
https://github.com/openjdk/jdk/blame/master/test/hotspot/jtreg/compiler/codegen/TestTrichotomyExpressions.java

It is one of the slowest compiler tests in tier1, takes over 30sec.

Looks like high iteration count is the problem.

Wait with this for now, as the test might get rewritten for JDK-8211518.
