- 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.
