The problem is that you don't need IPA info for every function
declaration we ever produce. C++ frontend produce tons of dead
declarations and I think that you don't need the data at all for
function not having their bodies available, so we actually need the data
for quite small fraction of all function decls we ever produce.
We probably might get better around with variables if we had static
variable inherited from variable with some extra fields...
