[jdk17u-fix-request] Approval Request from Satyen Subramaniam for backport. Adjusts code to call PhaseValues::intcon(), which is required so the node is properly entered in the GVN's hash table and its type is properly recorded in the GVN's type table Risk: Medium. Change to compiler code which can have broader impact. Change was merged in April 2024 and present in 23, which mitigates risk. Testing: * GHA Sanity Checks * Tier 1 and 2 tests locally
