Constructs a sentinel.
1) Default constructor. Value-initializes the underlying sentinel and the pointer to predicate.
2) Initializes the underlying sentinel with end and the pointer to predicate with pred.
3) Conversion from /*sentinel*/<false> to /*sentinel*/<true>. Copy constructs corresponding members.
Parameters
| end | - |  a sentinel representing the end of (possibly const-qualified) V
 | 
| pred | - | a pointer to predicate | 
| i | - | a /*sentinel*/<false> |
