to determine when branch operations are live. It adds a new fix-up
phase to correct update phi-nodeswhen control flow changes.
Below are compile time and performance impacts based on Facebook
internal code sets.
Baseline ADCE compared to new ADCE compile time, -O3 removing loops
Comparing compile times for ~400 source files from folly code base
"baseline" is total time in seconds for all...
