These tests were all using WpfFact, but not actually doing anything
that required either WPF or an STA thread. We plan to enable
parallelization of Facts (but not WpfFacts), and this ensures we can
parallelize as many tests as possible.

The code generator no longer checks for accessibility when deciding if it
should generate a getter or a setter.  There are many cases where we
generate code that is inaccessible in the hope that the user can fix the
accessibility problem later.
