OK? Bootstrapped and tested on powerpc-apple-darwin with no regressions.

Just to reply to my own patch, this happens at least once while compiling PR 8361 in the libstdc++ headers. This is both a compile time improvement and a missed-optimization as we are getting rid of some extra edges and CASE_LABEL_EXPR and it does not cost almost nothing extra as we do today.

Thanks,
