BigTIFF support fails when using 64-bit TIFF subdirectories

PS fails to load BigTIFF images that use a 64-bit directory offset.

You can download an example of such images here:
In the linked ZIP archive, the files "BigTIFFSubIFD4.tif" and "BigTIFFSubIFD8.tif" are identical except one uses a 32-bit directory and one uses a 64-bit directory. Both of them should load successfully, however Photoshop can only load the 32-bit version.

This bug also manifests when TIFF files have EXIF data included, due to the same cause.
