stage2: more InternPool related fixes

 * make Sema.zirPtrType coerce the sentinel value against the element
   type
 * fix lazyAbiAlignment wrong result type
 * typeHasOnePossibleValue no longer tries to create interned enum tag
   value with integer zero, instead uses enum_field_index
 * Type.ptr avoids trying to store typed null values into the intern
   pool
