pb_eo must be handled as a rip relative address for MSVC64, so an
intermediate register is needed. Should fix link failures.

timing results:
8380x3032 255x185

after: 139232 1996
Actually jumping to the proper version depending on the alignment:
8380x3032: 138767
A 0.5% speed improvement for gigantic images is not worth the code
duplication.
