Cleanup test utilities in JvmResolveUtil and GenerationUtils

Simplify usages and fix some warnings along the way.

Rename:
- analyzeFilesWithJavaIntegration, analyzeOneFileWithJavaIntegration -> analyze
- analyzeFilesWithJavaIntegrationAndCheckForErrors,
  analyzeOneFileWithJavaIntegrationAndCheckForErrors -> analyzeAndCheckForErrors
- compileFilesGetGenerationState, compileManyFilesGetGenerationStateForTest ->
  compileFiles
- compileFileGetGenerationStateForTest -> compileFile
- compileFileGetClassFileFactoryForTest -> compileFileTo
