zhangyunhao ebe1435fbb runtime: add fastrand64 
Support fastrand64 in the runtime, although fastrand uses wyrand to generate 64-bit random number, it still returns uint32. In some cases, we need to generate a 64-bit random number, the new API would be faster and easier to use, and at least we can use the new function in these places:

src/net/dnsclient.go:randInt()
src/hash/maphash/maphash.go:MakeSeed()
src/runtime/map.go:mapiterinit()

name                 time/op
Fastrand-16          0.09ns ± 5%
Fastrand64-16        0.09ns ± 6%
