Do not output error diagnostics when there is an infoset
- In cases where a element in a sequence's prefix separator is not found
use the AbsentRep error instead of MissingSeparator. This causes us to
reset to a PoU rather than just continuing - throwing out the error
from finding out of scope separators.
- Discard error messages caught in the ScalarParser section of parse
under cases where we were using setSuccess to mask errors. When
masking errors, we also need to mask related diagnostics.
- Add assert.invariant to catch any errors in the TDML runner if we also
return an infoset.
- Modify delimiterParser to not create PE errors when returning
AbsentRep.
- Add commented out tests related to discriminated unordered sequences
that show incorrect behavior that fixing this made more obvious.
