Matthew Jasper a1d0266878 Generate MIR thats easier for llvm for str matches 
LLVM appears to prefer (spend less time optimizing) long if chains if
it receives them in approzimately source order.
This fixes a ~10% regression for optimized builds of the encoding benchmark
on perf.rlo due to the changes to decision tree construction.
