Daniel Martí f80e270bab encoding/gob: avoid pointers to fieldType 
fieldType is a struct with only a string and an integer,
so its size will barely be three times that of a pointer.

The indirection doesn't save us any memory or append/grow cost,
but it does cause a significant amount of allocations at init time.
