  -----------
  [Analysis] resolveAllCalls - fix use after std::move warning. NFCI.

We can't use Use.Calls after its std::move()'d to TmpCalls as it will be in an undefined state. Instead, swap with the known empty map in TmpCalls so we can then safely emplace_back into the now empty Use.Calls.

Fixes clang static analyzer warning.
