Checked, the additional slack space for alignment is still needed for the `compiler/arguments/TestCodeEntryAlignment.java` that tries large `CodeEntryAlignment`-s. `CodeEntryAlignment*2` is too much. `HeapWordSize * 2` is not enough. `HeapWordSize + CodeEntryAlignment` fits the intent of the patch. See new commit.
