The swift frontend needs to be able to look up PGO function name variables based on the original raw function name. That's because it's not possible to create PGO function name variables while emitting swift IR. Instead, we have to create the name variables while lowering swift IR to llvm IR, at which point we fix up all calls to the increment intrinsic to point to the right name variable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@263662 91177308-0d34-0410-b5e6-96231b3b80d8
