When we relaxed the requirement for pattern matching open types to a
constant pattern to not require a conversion from the pattern expression
to the open type, but the pattern expression should be required to have
a constant value.

If a ruleset file changed, we didn't always reapply the new values
in the IDE. For legacy projects the IDE is taking the ruleset files
and applying them to the compilation; for CPS projects that's being done
when we call into the compiler to parse the command line string. We
forgot to reparse the command line string, so CPS projects wouldn't
refresh until some other command line string changed or the project
was unloaded or reloaded.
