This commit fixes an internal compiler error (ICE) that occurs when rustdoc attempts to process macros with a remapped filename. The issue arose during macro expansion when the `--remap-path-prefix` option was used. Instead of passing remapped filenames through, which would trigger the "attempted to remap an already remapped filename" panic, we now extract the original local path from remapped filenames before processing them. A test case has been added to verify this behavior. Fixes #138520 Signed-off-by: Charalampos Mitrodimas <charmitro@posteo.net>
