Change type from auto to size_t to fix warning.

[dsinclair]

Summary

The GetNumIVars() call returns a size_t, there is currently a warning being issue that it is being compared to int. It looks like the auto is getting type int. This CL makes it explicit that we're iterating over things of type size_t.
