This class represents a basic block.
This class represents a basic block. Each basic block contains a list of instructions that are either executed all, or none. No jumps to/from the "middle" of the basic block are allowed (modulo exceptions).
This class represents the intermediate code of a method or other multi-block piece of code, like exception handlers.

Represents a method in ICode.
Represents a method in ICode. Local variables contain both locals and parameters, similar to the way the JVM 'sees' them.
Locals and parameters are added in reverse order, as they are kept in cons-lists. The 'builder' is responsible for reversing them and putting them back, when the generation is finished (GenICode does that).
This class represents an instruction of the intermediate code.
This class represents an instruction of the intermediate code. Each case subclass will represent a specific operation.

A simple linearizer which predicts all branches to take the 'success' branch and tries to schedule those blocks immediately after the test.
A simple linearizer which predicts all branches to take the 'success' branch and tries to schedule those blocks immediately after the test. This is in sync with how 'while' statements are translated (if the test is 'true', the loop continues).

Linearize code in reverse post order.
Linearize code in reverse post order. In fact, it does a post order traversal, prepending visited nodes to the list. This way, it is constructed already in reverse post order.

This class represents a type kind.
This class represents a type kind. Type kinds represent the types that the VM know (or the ICode view of what VMs know).

Equivalent to x.hashCode except for boxed numeric types and null.
Equivalent to x.hashCode except for boxed numeric types and null.
For numerics, it returns a hash value which is consistent
with value equality: if two value type instances compare
as true, then ## will produce the same hash value for each
of them.
For null returns a hashcode where null.hashCode throws a
NullPointerException.

The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).
The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

Cast the receiver object to be of type T0.
Cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics.
Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at
runtime, while the expression List(1).asInstanceOf[List[String]] will not.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the requested type.

Tests whether the argument (that) is a reference to the receiver object (this).
Tests whether the argument (that) is a reference to the receiver object (this).
The eq method implements an equivalence relation on
non-null instances of AnyRef, and has three additional properties:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.x of type AnyRef, x.eq(null) and null.eq(x) returns false.null.eq(null) returns true. When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).
true if the argument is a reference to the receiver object; false otherwise.

well as the interaction between finalize and non-local returns
and exceptions, are all platform dependent.

Test whether the dynamic type of the receiver object is T0.
Note that the result of the test is modulo Scala's erasure semantics.
Therefore the expression 1.isInstanceOf[String] will return false, while the
expression List(1).isInstanceOf[List[String]] will return true.
