Nathan Lanza 220e77a83a [clang][CodeGenPGO] Don't use an invalid index when region counts disagree ...

If we're using an old instrprof profile and the user passes we can get
Decls with children decl counts not matching the what the profile was
written against. In a particular case I was debugging we have 24 decls
in the AST and 22 decls in the profile. Avoid crashing in this case.
