This error was found when analyzing MySQL with CTU enabled. When there are space characters in the lookup name, the current delimiter searching strategy will make the file path wrongly parsed. And when two lookup names have the same prefix before their first space characters, a 'multiple definitions' error will be wrongly reported. e.g. The lookup names for the two lambda exprs in the test case are `c:@S@G@F@G#@Sa@F@operator int (*)(char)#1` and `c:@S@G@F@G#@Sa@F@operator bool (*)(char)#1` respectively. And their prefixes are both `c:@S@G@F@G#@Sa@F@operator` when using the first space character as the delimiter. Solving the problem by adding a length for the lookup name, making the index items in the format of `<USR-Length>:<USR File> <Path>`. --- In the test case of this patch, we found that it will trigger a "triple mismatch" warning when using `clang -cc1` to analyze the source file with CTU using the on-demand-parsing strategy in Darwin systems. And this problem is also encountered in D75665, which is the patch introducing the on-demand parsing strategy. We temporarily bypass this problem by using the loading-ast-file strategy.
