JDK-8284115 - [IR Framework] Compilation is not found due to rare safepoint while dumping PrintIdeal/PrintOptoAssembly
Description
The VM sometimes prints "<!-- safepoint while printing -->" in the middle of emitting the PrintIdeal or PrintOptoAssembly output which could lead to test failures.

This is rare but was already observed twice so far. Once in the converted Valhalla tests and once while running the framework internal TestIRMatching.java test.
Comments
Fix request [17u] I backport this for parity with 17.0.7-oracle. No risk, only a test change. Clean backport. Tests pass. SAP nightly testing passed.
