[Roland Mesde]

Backporting JDK-8325482: Test that distinct seeds produce distinct traces for compiler stress flags.

This PR adds test to verify that different seeds produce distinct traces for compiler stress flags, and fixes macro node generation issue.

For parity with Oracle JDK.

Ran related tests on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

make test TEST=test/hotspot/jtreg/compiler/debug/TestStress.java
make test TEST=test/hotspot/jtreg/compiler/debug/TestStressDistinctSeed.java
