Test suites for Dialyzer
This is a transcription of most of the cvs.srv.it.uu.se:/hipe repository dialyzer_tests into test suites that use the test server framework. See README for information on how to use the included scripts for modifications and updates. When testing Dialyzer it's important that several OTP modules are included in the plt. The suites takes care of that too.

+%%% A module with an erroneous record field declaration which mixes up
+%%% structured and opaque terms and causes a crash in dialyzer.
+%%%
+%%% In addition, it revealed that the compiler produced extraneous
+%%% warnings about unused record definitions when in fact they are
+%%% needed for type declarations. This is now fixed.
