Subject: Tell the diagnostic client about starting and ending source files when automatically... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0ab547c284285e8abc31b30ded2226eb78c2af3b;p=clang

Tell the diagnostic client about starting and ending source files when automatically creating chained PCHs. This way, we don't get a crash whenever a diagnostic is emitted while processing the include.
