Most test cases test for getBuildConfiguration().parallelJS. Some test for this.hasOwnProperty("TypedObject") and then assumes that TO arrays will have a mapPar method; this is wrong. We should also remove utility code used by the test cases.

Additionally: - older tests (which have not been run for a long time) compare "typeof ParallelArray" to undefined. - some test cases mix parallel and non-parallel tests and must be edited suitably.

Additionally, Array.prototype.build is not ES6 and is only defined in SpiderMonkey when PJS is enabled. Some test cases test for this by testing for TypedObject though (different pattern than listed above).

Said bug is the assumption that TypedObject implies Array.build is available.
