This file defines the SmallVector class.

This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

StringRef - Represent a constant reference to a string, i.e.

ArgList - Ordered collection of driver arguments.

A concrete instance of a particular driver option.

OptSpecifier - Wrapper class for abstracting references to option IDs.

Provide access to the Option info table.
