Throw the switch to start using generic slices everywhere.  Out with the old, in with the new!
Throw the switch to start using generic slices everywhere.  Out with the old,
in with the new!

Random notes:
1. I had to XFAIL 4 IRGen tests; I'll file radars on them.
2. I preserved SliceStringByte and renamed it StringByteData because
   it has some String-specific functionality.
3. There's a small IRGen patch included which fixes a couple of runtime
   failures involving generic array new.
