This patch is currently for display only.
The aim of the patch is to make it easier to test the effectiveness of the feature hasMultipleConditionRegisters in a target as such feature is set statically in the target lowering info and influences optimization in several places.
This patch adds the llc option -has-multiple-condition-registers=0/1.
It doesn't change the codegen behaviour.
