Hi,
As shown in PR104967, for some overload built-in function instance,
if it requires a date type which isn't defined on the target, its
fntype would be initialized as NULL. This patch is to consider
this possibility in function find_instance to avoid ICE.
Bootstrapped and regtested on powerpc64-linux-gnu P8 and
powerpc64le-linux-gnu P9 and P10.
Is it ok for trunk?
BR,
Kewen
