[cfe-commits] Somewhat outdated documentation

[Ted Kremenek]

Great observation.  Actually the document needs to be rephrased that PTH is largely a mechanism now for doing performance analysis of the frontend by reducing lexing time to help find the other "hot" parts of the compiler.

This approach would theoretically have the same constant-time algorithmic advantages just mentioned but would also retain some of the strengths of PTH such as reduced memory pressure (ideal for multi-core builds)."
