4423f1a3fd Do not assert, when case range split metric is zero and JTs are not allowed: just emit binary tree in this case. This 
fixes PR1403.

062b15b7cc Make a preemptive bitcode format change to support PR1146. This lets us do 
pr1146 in llvm 2.1 without ugly code to emulate old behavior.  This should
be merged into the 2.0 release branch.
