There was an alias between 'simplifycfg' and 'simplify-cfg' in the PassRegistry. That was the original reason for this patch, which effectively removes the alias. This patch also replaces all occurrances of 'simplify-cfg' by 'simplifycfg'. Reason for choosing that form for the name is that it matches the DEBUG_TYPE for the pass, and the legacy PM name and also how it is spelled out in other passes such as 'loop-simplifycfg', and in other options such as 'simplifycfg-merge-cond-stores'. I for some reason the name should be changed to 'simplify-cfg' in the future, then I think such a renaming should be more widely done and not only impacting the PassRegistry.
