Skip debuginfo intrinsic in markLiveBlocks.
Summary:
The optimizer is 10%+ slower with vs without debuginfo. I started checking where
the difference is coming from.
I compiled sqlite3.c with and without debug info from CTMark and compare the time difference.
I use Xcode Instrument to find where time is spent. This brings about 20ms, out of ~20s.
