// A union that describes the entries of the vector table. The union is needed
// since the first entry is the stack pointer and the remainder are function
// pointers.
//
// Normally the vectorTable below would require entries such as:
// { .topOfStack = x },
// { .ptrToHandler = y },
// But since ptrToHandler is defined first in the union, this is the default
// type which means we don't need to use the full, explicit entry. This makes
// the vector table easier to read because it's simply a list of the handler
// functions. topOfStack, though, is the second definition in the union so
// the full entry must be used in the vectorTable.
