[Bug lto/53282] lto and visibility-inlines-hidden makes "wrongly" hidden symbols and in a way that depends on the order of the input compilation units

Hi Honza,
I forgot to say that I tried both 
-flto-partition=1to1
and
-flto-partition=none
with the same result

the point is that the symbols in question refers to a templated function
explicitly defined as
template  edm::eventsetup::EventSetupRecordKey
edm::eventsetup::heterocontainer::makeKey<_recordclassname_,
edm::eventsetup::EventSetupRecordKey>()

in the attached there are three of those: only one is hidden.
In the "real" library there are 307 of those, only 7 are hidden!
SO I suspect some sort of bug in lto

I will try to produce a synthetic test
