[PATCH] D135425: [InstrProf] Disable marking COMDAT profd variable as private linkage

I agree that the current setup is problematic for ThinLTO. I think we can retain the current size optimization of private profd (suppressing the symbol table entry). D135427 <https://reviews.llvm.org/D135427> tries to fix this on the FunctionImport side.
`clang -O2 -fuse-ld=lld -fprofile-generate=./t m1.o m2.o -flto=thin -o t_gen` will work.
