[SIL] Generalize CastingIsolatedConformances to CheckedCastInstOptions

Browse Source 
We are going to need to add more flags to the various checked cast
instructions. Generalize the CastingIsolatedConformances bit in all of
these SIL instructions to an "options" struct that's easier to extend.

Precursor to rdar://152335805.
