Using a _BitInt (or _ExtInt) type as a block parameter or block return type hits an "unreachable" when trying to determine the encoding for the block. Instead of crashing, this patch handles it like some of the other types for which we don't yet have an encoding. The test case verifies we no longer crash, but does not verify that we provide any particular encoding (it can be updated once someone more familiar with ObjC steps in to define the encoding). Fixes PR50503.
