compiler/debug/TestStressCM.java and compiler/debug/TestStressIGVNAndCCP.java fail with "java.lang.RuntimeException: got different [CCP/code motion] traces for the same seed..."

The regression seems to be due to the introduction of non-determinism in the node dumps of otherwise identical compilations.

E.g. one run dumps

282 ConI \=\=\= 0 [[ 229 ]] \#int\:6 java/lang/Class (java/io/Serializable,java/lang/constant/Constable,java/lang/reflect/AnnotatedElement,java/lang/invoke/TypeDescriptor,java/lang/reflect/GenericDeclaration,java/lang/reflect/Type,java/lang/invoke/TypeDescriptor$OfField)\:exact *

while the next (identical) run dumps

282 ConI \=\=\= 0 [[ 229 ]] \#int\:6 java/lang/Class (java/lang/reflect/AnnotatedElement,java/lang/invoke/TypeDescriptor,java/lang/reflect/GenericDeclaration,java/lang/reflect/Type,java/lang/invoke/TypeDescriptor$OfField,java/io/Serializable,java/lang/constant/Constable)\:exact *

So far, the failure has only been observed in macosx builds (both x64 and aarch64).
