Check if the SmallSet contains the given element.
std::pair< const_iterator, bool > insert(const T &V)
insert - Insert an element into the set if it isn't already there.
StringRef - Represent a constant reference to a string, i.e.
Target - Wrapper for Target specific information.
Triple - Helper class for working with autoconf configuration names.
Represents a version number in the form major[.minor[.subminor[.build]]].
