Adds diagnostics for missing opportunities of indirect call promotion.

[netforce]

Summary

Some indirect branches that are important for performance might not
be promoted because there are too many targets and/or they don't have enough
counts to be promoted. Let's make them easier to understand by adding
diagnostics for such opportunities.

llvm/lib/Transforms/Instrumentation/IndirectCallPromotion.cpp

if (ICallProfDataRef.size() > NumCandidates &&
           R << ore::NV("NumCandidates", NumCandidates)
             << " candidates were chosen and remaining are not profitable, ";
         }
         R << "but hasn't reached desired coverage "
           << ore::NV("ICPMissingPercentThreshold", ICPMissingPercentThreshold)
           << "\% for a hot indirect call, and "
           << ore::NV("Candidates", ICallProfDataRef.size() - NumCandidates)
           << " candidates left with remaining count "
-          << ore::NV("RemainingCount", RemainingCount)
-          << " out of total count " << ore::NV("TotalCount", TotalCount) << " (";
+          << ore::NV("RemainingCount", RemainingCount) << " out of total count "
+          << ore::NV("TotalCount", TotalCount) << " (";
         for (uint32_t I = NumCandidates; I < ICallProfDataRef.size(); I++) {
           if (I != NumCandidates) {
             R << ", ";
           }
           uint64_t Target = ICallProfDataRef[I].Value;
           StringRef Name = Symtab->getFuncName(Target);
           if (Name.empty()) {
             R << ore::NV("Target md4sum", Target);
