[clang][nfc] Update some documentation referring to old clang flags

-cfg-dump and -cfg-view were removed long ago. The rest are gone, but
I'm opting not to remove these lines without finding a replacement.

 Of course, viewing the CFG (Control-Flow Graph) is also useful:
 
-$ clang -cc1 -help | grep cfg
- -cfg-add-implicit-dtors Add C++ implicit destructors to CFGs for all analyses
- -cfg-add-initializers   Add C++ initializers to CFGs for all analyses
- -cfg-dump               Display Control-Flow Graphs
- -cfg-view               View Control-Flow Graphs using GraphViz
- -unoptimized-cfg        Generate unoptimized CFGs for all analyses
-
--cfg-dump dumps a textual representation of the CFG to the console,
-and -cfg-view creates a GraphViz representation.
