make two compiler options explicit for Visual Studio projects

This patch changes the release configuration of MS VS projects to
explicitly use two compiler options "Maximize Speed (/O2)" and
"Favor fast code(/Ot)".

This change was back ported from the master branch, with the
additional change to remove a dependency on obj_int_extract.bat
