do not use compiler.getSourceManager().getFilename()

This is a continuation of ff002524c12471668e63837a804b6006f9136a34.
When compiling with icecream, its -frewrite-includes merges
all #include's into one .cxx file and marks them with with line
markers. But SourceManager::getFilename() doesn't take those
into account and so it reports all of those as <stdin>.
So use getFileNameOfSpellingLoc(), which explicitly handles this
case.
And we should probably never ever use SourceManager::getFilename().
