Detailed Description
A p-code emitter for building PcodeOp objects.
The emitter is attached to a specific Funcdata object. Any p-code generated (by FlowInfo typically) will be instantiated as PcodeOp and Varnode objects and placed in the Funcdata dead list.

The main pcode emit method.
A single pcode instruction is returned to the application via this method. Particular applications override it to tailor how the operations are used.
- Parameters
-
addr is the Address of the machine instruction opc is the opcode of the particular pcode instruction outvar if not null is a pointer to data about the output varnode vars is a pointer to an array of VarnodeData for each input varnode isize is the number of input varnodes
Implements PcodeEmit.
