ef8dc9d240 gotest: increase the test timeout

and the current default timeout duration of gofrontend is 240 seconds,
which is not long enough for some big tests. This CL changes it to
600s, so that all tests have enough time to complete.

10172a64ce compiler, runtime, reflect: generate hash functions only for map keys 
Right now we generate hash functions for all types, just in case they
    are used as map keys. That's a lot of wasted effort and binary size
    for types which will never be used as a map key. Instead, generate
    hash functions only for types that we know are map keys.
    
    Just doing that is a bit too simple, since maps with an interface type
    as a key might have to hash any concrete key type that implements that
    interface. So for that case, implement hashing of such types at
    runtime (instead of with generated code). It will be slower, but only
    for maps with interface types as keys, and maybe only a bit slower as
    the aeshash time probably dominates the dispatch time.
    
    Reorg where we keep the equals and hash functions. Move the hash function
    from the key type to the map type, saving a field in every non-map type.
    That leaves only one function in the alg structure, so get rid of that and
    just keep the equal function in the type descriptor itself.
    
    While we're here, reorganize the rtype struct to more closely match
    the gc version.
    
    This is the gofrontend version of https://golang.org/cl/191198.
