Provide a standard-compliant in place construction tag types.

Classes:

bsl::in_place_t

tag type for in-place construction

Description:

This component provides an implementation of a standard compliant tag type for in-place construction, bsl::in_place_t. This tag type is used in constructors of bsl::optional to indicate that the contained object should be constructed in-place. Note that the standard currently has two other in-place construction tag types, std::in_place_type_t and std::in_place_index_t. There is currently no need to provide the equivalent tag types in bsl, but if such need arises, the name of this header has been chosen for the purpose of being the designated place for all in-place construction tags.
