Please review.

There are a lot of calls to this method that all need to be changed. Please be
thorough in finding all instances of int64 that need to be changed.

You mean wherever GloballyFindByID() function is being called, I need to change.

There are more calls to frame_tree_node_id() than you've covered in your CL.
Please do a thorough search through the codebase and include them all in the CL.
You can use cs.chromium.org to facilitate searching.
