Function FormatCompilerIndependentFileLocation

tests/gtest/gtest-all.cc:10740–10748

Formats a file location for compiler-independent XML output. Although this function is not platform dependent, we put it next to FormatFileLocation in order to contrast the two functions. Note that FormatCompilerIndependentFileLocation() does NOT append colon to the file location it produces, unlike FormatFileLocation().
