Add assembly output - for comparison purposes

- Add assembly output flags to build process
- Remove sz argument from WP_TEST_BEGIN and WP_TEST_END
- Stop being dumb, remove loop in wp_test_suite_new since we have a
  wp_suites_count offset :-/
- Fix several bugs and off-by-one errors in loops
- Change some for loops to do-while for clarity
Clean up generated PDF documentation

- Add keyword match for restrict in tegen.w
- Replace textual instances of wp\_test.c with |wp_test.c|
- Remove *wp_test_suite_test_pt from typedef; this will be common as
  we'll be cleaning up quite a bit of cruft
- Add CWEB control codes to assist with formatting
