Added preparser strict-mode tests.

Added preparser strict-mode tests. 

Now tests for use of eval, arguments, reserved words and with statement.

Mostly test cases.
I really should make them templated.

LGTM

But I would use eval and try-catch to reduce the number of files. All of this
could be tested easily in one file? If getting the preparser to kick in for eval
is a problem you could put in a testing flag for that.

Address review comments.

Sadly, using eval won't work. This is testing the stand-alone preparser library,
so there is no V8 and no javascript execution capability.

I have a python-based template solution that's almost working. It should cut
down on the test-files while increasing coverage (e.g., test all future reserved
words).

Done.
