[Basic] getColumnNumber returns location of CR+LF on Windows

When fixing a Clang-Tidy bug in D31406,
reuse of FileID enabled the missing highlightRange function.
Assertion in highlightRange failed because the end-of-range column
number was 2 + the last column of a line on Windows.
This fix is required to enable D31406.
