Yes, the following test use one or both of the `AlwaysActAsServerClassMachine` and `NeverActAsServerClassMachine` flags. I've run them all locally to see that they are not affected by the deprecation warning that is printed when using the flag after this patch.

test/hotspot/jtreg/gc/arguments/TestSelectDefaultGC.java
test/jdk/jdk/jfr/event/compiler/TestCompilerPhase.java
test/hotspot/gtest/runtime/test_globals.cpp

I didn't mention in the PR summary, but I've also run tier1-2 for sanity.
