fixed reporting issue and de-duplication issues.

There were some issues getting xunit to respect the -notrait option
hence we decided to simplify and use ConditionalFact

This change allows provides the option of running our tests in 64 bit
mode.  Simply invoke BuildAndTest.proj in the following manner:

> msbuild /v:m /m BuildAndTest.proj /p:Test64=true

There are a set of tests today that don't run correctly in 64.  All have
been annotated with the trait

> Require32=true

We need to push on these to get a clean 64 bit run.  But short term this
will at least give us protection against regressions.
