[InstrProf] Fix promoter when using counter relocations
When using counter relocations, two instructions are emitted to compute
the address of the counter variable.
```
%BiasAdd = add i64 ptrtoint <__profc_>, <__llvm_profile_counter_bias>
%Addr = inttoptr i64 %BiasAdd to i64*
```
When promoting a counter, these instructions might not be available in
the block, so we need to copy these instructions.
