Run V8 spec conformance test suite (#243)
The shell script runs the tests and diffs stdout against v8.txt.
Lines added/removed means tests were broken/fixed.

Future work is to a) fix failing tests, and b) enable more tests.

A number are disabled for various reasons and mjsunit subdirectories are
currently skipped. Need to decide on a case-by-case basis what is and
isn't relevant to us.

At the moment about 430 tests are run of which approx. 80% pass.
