7b91df38 - [OMPIRBuilder] Don't use invalid debug loc in reduction functions. (#147950)

[OMPIRBuilder] Don't use invalid debug loc in reduction functions. (#147950) We have this pattern of code in OMPIRBuilder for many functions that are used in reduction operations. ``` Function *LtGRFunc = Function::Create BasicBlock *EntryBlock = BasicBlock::Create(Ctx, "entry", LtGRFunc); Builder.SetInsertPoint(EntryBlock); ``` The insertion point is moved to the new function but the debug location is not updated. This means that reduction function will use the debug location that points to another function. This problem gets hidden because these functions gets inlined but the potential for failure exists. This patch resets the debug location when insertion point is moved to new function. Some `InsertPointGuard` have been added to make sure why restore the debug location correctly when we are done with the reduction function.
