Skip tests that fail on windows and enable all the rest (#3035)

This lets us run most tests at least on that platform.

Add a new function for skipping those tests, skip_if_on_windows,
so that it's easy to find which tests are disabled on windows for later fixing
efforts.

This fixes a few minor issues for windows, like comparisons
should ignore \r in some cases.

Rename all passes tests that use --dwarfdump to contain "dwarf"
in their name, which makes it easy to skip those (and is clearer
anyhow).
