introduce static type warnings in certain dart libraries. I wanted this for dart:io and might as well add it for the other libraries that have no warnings when analyzed. This required a bit of test script reworking. dartc used a leading hash in a file to determine if it was a test. That is now broken and has been removed. This also allowed me to override the readOptionsFromFile method in test suites so that certain analyzer test suites can require all tests to be static clean.
