[lworld] RFR: 8354408: [lworld] compiler/types/TestSubTypeCheckUniqueSubclass.java IR mismatches post jdk-25+16 merge

Thu May 1 05:15:35 UTC 2025

Hi,

The issue here is that `IRNode::macroNodes` takes a full line regex, not only the node name part like `IRNode::beforeMatchingNameRegex`. As a result, we should compute the full regex for `SUBTYPE_CHECK`.

Please kindly review, thanks a lot.
