bool | operator== (const TypeLoc &LHS, const TypeLoc &RHS) |

Base wrapper for a particular "section" of type source info.
A client should use the TypeLoc subclasses through castAs()/getAs() in order to get at the actual information.
The kinds of TypeLocs.
Equivalent to the Type::TypeClass enum, except it also defines a Qualified enum that corresponds to the QualifiedLoc class.

It will consider type adjustments from a type that was written as a T to another type that is still canonically a T (ignores parens, attributes, elaborated types, etc).
