Summary: This adds support for auto-detection of path style to SymbolFileBreakpad (similar to how r351328 did the same for DWARF). We guess each file entry separately, as we have no idea which file came from which compile units (and different compile units can have different path styles). The breakpad generates should have already converted the paths to absolute ones, so this guess should be reasonable accurate, but as always with these kinds of things, it is hard to give guarantees about anything. In an attempt to bring some unity to the path guessing logic, I move the guessing logic from inside SymbolFileDWARF into the FileSpec class and have both symbol files use it to implent their desired behavior.
