Reads an DefIfElse structure from the AML byte stream.
A DefIfElse structure is defined as DefIfElse := IfOp PkgLength Predicate TermList DefElse.
Note that the the DefIfElse structure is also used for normal If statements, just without a "Else" part, this is because the DefElse part is optional.

Reads a DefWhile structure from the AML byte stream.
A DefWhile structure is defined as DefWhile := WhileOp PkgLength Predicate TermList.
The While statement works by evaluating the Predicate, if it is a non-zero integer, the TermList following the Predicate is executed, then the Predicate is evaluated again, this continues until the Predicate evaluates to zero.
