I totally agree with what eugenis said.
I added his comments to a TODO comment.
I will commit this version and may address the TODO later.

Thanks for improving this.

Sorry it takes long to review this.
I have a pending patch that value profiling the expensive MOD/REM instructions. It is more tightly coupled to edge profile (than current mem-size-op and icall value profile).
The difference is that it does not have <valuesite, value> pair. The counts are stored like the edge counts.
It seems to be fine with patch as the instrumentation says in PGOInstrumenation.cpp and only the candidate collecting is extracted out.

For the legacy pass manager, use option "-mllvm -debug-pass=Structure", or in the source, we add the lowering pass right after instrumentation pass.
LGTM. Thanks for the fix!

Sent the wrong test file in last patch.
Update to the correct one.

they are not doing the exacly the same thing for old pass manager and new pass manger: old pass manger is doing instrumentation, while the new pass manager with this change is NOT.
the test is not check instrumentation, (it only check the variables that generates by InstroProfiling pass).
In this sense, the test is not well written.
This patch does not make sense to me.

My previous patch was not complete -- we need to set the profile count to the fail-to-instrument edge. Otherwise, we cannot propagate the counts in the CFG.
The new patch has this part of change.
Updated the test to test the profile-use.

Another change of this patch is to move down statistic collection code for critical edge. I think this is a better place.
looks good to me.

Adjusted the output string with David's comments.
Also made the naming more uniformed for edge and value profiles.
Discussed offline with David. We changed the output to a simpler: "Description: <Value>" format. This tool will mostly used in a script. Simpler format will make text grep cleaner.
