Cache reflect.MethodByName
The isolated benchmark for the function is obviously much faster:
```bash
name old time/op new time/op delta
GetMethodByName-10 1.21µs ± 7% 0.23µs ± 5% -81.42% (p=0.029 n=4+4)
name old alloc/op new alloc/op delta
GetMethodByName-10 680B ± 0% 0B -100.00% (p=0.029 n=4+4)
name old allocs/op new allocs/op delta
GetMethodByName-10 20.0 ± 0% 0.0 -100.00% (p=0.029 n=4+4)
```
But more pleasing is the overall performance looking at the site benchmarks:
```bash
name old time/op new time/op delta
