Assuming you are talking about map_variable_attnos(), it's always been
in rewriteManip.c / rewriteManip.h since it was added by 541ffa65c32.

While reviewing this patch, I had the idea of moving it to the new
header attmap.h, but thought it might be a good idea to keep attmap.c
limited to just building the maps and not move into it other functions
that do something useful with those maps, like translating expression
trees, converting tuples, etc.
