[TableGen] Re-work FactorNodes to avoid an extra temporary vector.

Instead of copying elements to the NewOptionsToMatchVector, we
now shift down elements in OptionsToMatch as we create holes by
pulling out equal matchers. After we finish processing the vector,
we'll trim the size to just the elements that are still in use.
