Pull request overview

This PR fixes nondeterministic bytecode output by ensuring covariant bridge methods added by Verifier are emitted in discovery order (rather than HashMap iteration order), improving reproducibility of generated .class files for identical sources.

Changes:

• Switches the internal bridge-method collection maps in Verifier.addCovariantMethods from HashMap to LinkedHashMap to preserve insertion order during iteration.
• Adds a regression test that compiles a sample class with multiple covariant overrides and asserts the resulting bridge method order in the class file.

File	Description
src/test/groovy/org/codehaus/groovy/classgen/CovariantBridgeMethodOrderTest.groovy	New regression test asserting deterministic, declaration-ordered bridge method emission by inspecting class bytes via ASM.
src/main/java/org/codehaus/groovy/classgen/Verifier.java	Uses insertion-ordered maps for collecting/iterating interface methods and bridge methods so emission order is stable and reproducible.
