* Compares the executable sections of the deployed and compiled bytecode, * ignoring differences in metadata, library link references, immutable * variables, and call protection placeholders. * * This is necessary because deployed bytecode contains dynamically inserted * values (e.g.

(compilerOutputBytecode: CompilerOutputBytecode)

   * equivalent, `false` otherwise.
