llvm-mirror/lib/Analysis/CGSCCPassManager.cpp
Chandler Carruth edb0b67c45 [PM] Remove the defunt CGSCC-specific debug flag.
Even before I sunk the debug flag into the opt tool this had been made
obsolete by factoring the pass and analysis managers into a single set
of templates that all used the core flag. No functionality changed here.
