Detailed Description

MCSymbol - Instances of this class represent a symbol name in the MC file, and MCSymbols are created and unique'd by the MCContext class. MCSymbols should only be constructed with valid names for the object file.

If the symbol is defined/emitted into the current translation unit, the Section member is set to indicate what section it lives in. Otherwise, if it is a reference to an external entity, it has a null section.
