Since pres != nil was already checked and the routine sets *pres to false
and returns, the subsequent tests are unneeded.

bug165.go:13:6: error: invalid recursive type 'S'

This is a different line from the 6g error message, which is
"invalid map key type".  I accomodated both compilers by
merging the line.

bug188.go:13:2: error: unexpected reference to package

I made the error message less specific, which I think is fine
here.

- renamed Z -> Int
- made Int ops methods on *Int
- "install" assembly routines dynamically
- replace mulVW functions with mulAddVWW
  of equivalent performance but symmetric functionality
  to divWVW
- implemented scanN

status:
- need mulNN (trivial)
- need division/modulo after which the set of
  elementary operations is complete
- to/from string conversion working
