`erase` overloads

== Synopses

Declared in `<bslalg_dequeprimitives.h>`

Call the destructor on each of the elements of a deque of parameterized `VALUE_TYPE` in the specified range `[first .. last)]`. Shift the elements to fill up the empty space after the erasure, using the smaller of the range defined by `[fromBegin .. first)]` and `[last .. fromEnd)]` after the erasure. Load in the specified `toBegin` and `toEnd` the new boundaries of the deque after erasure and return an iterator pointing to the element immediately following the removed elements. The behavior is undefined unless `fromBegin <= first <= last <= fromEnd`.

Same as the preceding `erase` overload for bitwise‐copyable types.

Call the destructor on each of the elements of a deque of parameterized `VALUE_TYPE` in the specified range `[first .. last)]`. Shift the elements from the smaller of the specified range `[fromBegin .. first)]` and `[last .. fromEnd)]` to fill up the empty spaces after the erasure. Load in the specified `toBegin` and `toEnd` the new boundaries of the deque after erasure and return an iterator pointing to the element immediately following the removed elements. The behavior is undefined unless `fromBegin <= first <= last <= fromEnd`. Note that the last argument is for removing overload ambiguities and is not used.
