[PATCH] D152490: [llvm-profdata] Use StringRef for CallTargetMap

[Mark Santaniello via Phabricator via llvm-commits]

marksantaniello added a comment.

Another thing worth considering is just to use const char* as the map key.  I believe it's safe in this case, and smaller than StringRef which is a pointer and a length.
