Rename snippet files to match the carved up corelib/tools/
This is a folllow-up to commits
548513a4bd050d3df0a85fed6e2d1a00ce06d2ab and
a9aa206b7b8ac4e69f8c46233b4080e00e845ff5, renaming the snippets files
referenced by the files moved out of corelib/tools/ to match the new
locations of the files using them.
