Is there a reason this is not done as part of pass_fold_builtins? (It
looks like
maybe adding this to fold_call_stmt in builtins.c would be sufficient
too).
As I feared, builtin folding occurs in several places. In particular its first
call is very early on in the host compiler, which is far too soon.
We have to defer folding until we know whether we're doing host or device
compilation.
