/**
 * This class represents a MSFT <b><code>ThrowInfo</code></b> symbol.  We have created this
 *  object and the <b><code>MDObjectReserved</code></b> type from which it is derived.  ThrowInfo
 *  seemingly has a structure as seen in the class layout of a 32-bit binary as follows:
 * <pre>
 *       class _s__ThrowInfo	size(16):
 *       +---
 *   0   | attributes
 *   4   | pmfnUnwind
 *   8   | pForwardCompat
 *  12   | pCatchableTypeArray
 *       +---
 * </pre>
 * We have seen symbols with double underscore (usually 32-bit binary) and single underscore
 *  (usually 64-bit binary), such as:<pre>
 *   mangled = "__TI1?AUX@@";
 *   or...
 *   mangled = "_TI1?AUX@@";
 * </pre>
