I don't know why it's not part of the standard library, but here is a piece
of code that does the job. (It's written in a slightly roundabout way to
make sure that the constants are untyped.)
const BitsPerWord = 32 << (^uint(0) >> 63) // either 32 or 64
const (
MaxInt = 1<<(BitsPerWord-1) - 1 // either 1<<31 - 1 or 1<<63 - 1
MinInt = -MaxInt - 1 // either -1 << 31 or -1 << 63
MaxUint = 1<<BitsPerWord - 1 // either 1<<32 - 1 or 1<<64 - 1
)
