Emit2ByteOpCodeInt16() private method

Emits a two byte opcode plus a 2-byte operand.
private Emit2ByteOpCodeInt16 ( byte opCode1, byte opCode2, int popCount, int pushCount, int emitInt16 ) : void
opCode1 byte The first byte of the opcode to emit.
opCode2 byte The second byte of the opcode to emit.
popCount int The number of items to pop from the stack.
pushCount int The number of items to push onto the stack.
emitInt16 int A 16-bit integer to emit.
return void
