Compiled methods can have up to 3 entry points that take different types
of parameters. For debugging purposes, it's useful to print the types of 
each
entry point.

The following example shows how the [Verified Entry Point] of a C1 method
shuffles the parameters before jumping to the [Verified Value Entry Point]:
