Xin Tong 074ccf32ce 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.
