RFR: 8320237 C2: late inlining of method handle invoke causes duplicate lines in PrintInlining output

[Kangcheng Xu]

This PR resolves [JDK-8320237](https://bugs.openjdk.org/browse/JDK-8320237)

The original behavior produces both a failure and success message upon late inlining which is confusing. The patch removes the failure message if inlining was successful. Huge thanks to @rwestrel for reporting and working out a solution.

Unit test `test/hotspot/jtreg/compiler/inlining/TestDuplicatedLateInliningOutput.java` is added and passing.
