Add test suite for the preparser.

Add test suite for the preparser.

The test suite builds the preparser test program and runs it on each .js file in
the test/preparser directory.
Currently it only checks that preparsing runs without crashing or erroring.
This also implicitly tests that the preparser library can be built.

TEST=test/preparser/*.js

Maybe remove the comment in parenthesis and make it a separate section of the
comment. It seems important enough to not be in parenthesis.
