Fix `specializeRTTIObject` to use non-zero RTTI value to work with `Optional`. (#8677)

2025-10-10T21:34:56+00:00

Closes #8673. The issue is that we use the RTTI field of an existential to check if it is null. We have the logic to help the user to fill in a non-zero value for the RTTI field when such an object is filled from the host. However, when there is slang code creating an existential value, we still have old logic in the compiler that just fills in 0 for the RTTI field, causing an `Optional.hasValue` to always return false in such cases.
