[DebugInfo][IndVarSimplify] Propagate source loc when simplifying rem (#135399)
When IndVarSimplify simplifies a rem of the induction variable to a cmp
and select, only the select currently receives the rem's source
location; this patch propagates it to the cmp as well.
Found using https://github.com/llvm/llvm-project/pull/107279.
