- Support "switch" statements over 64-bit integers

  (in CompCert C to Cminor, included)
- Translation of "switch" to decision trees or jumptables made generic
  over the sizes of integers and moved to the Cminor->CminorSel pass
  instead of CminorSel->RTL as before.
- CminorSel: add "exitexpr" to support the above.
- ValueDomain: more precise analysis of comparisons against an integer
  literal.  E.g. "x >=u 0" is always true.
