This info doesn't show what type of storage resource is used for implementing the buffer. That info can be found in the "source view" tab of the area report.

How can i implement a shfit register in OpenCL using the total_gin info?

Check "Intel FPGA SDK for OpenCL Programming Guide, Section 5.10.1 - Inferring a Shift Register". Note that unless accesses to the buffer are done in shifting manner, you will not be able to implement that buffer as a shift register.
