runtime: special case interface hashing for pointers
Interfaces often contain pointers. Implement a fast path for this case.
name old time/op new time/op delta
MapInterfaceString-16 21.4ns ±19% 20.5ns ±10% ~ (p=0.361 n=10+10)
MapInterfacePtr-16 25.8ns ± 8% 17.3ns ± 7% -33.11% (p=0.000 n=10+9)
Fixes #37086
