Since m_VtxDesc.Text7Coord is broken across a 32 bit word boundary, retrieve its value manually. If we didn't do this, the vertex format would be read as one bit offset from where it should be, making 01 become 00, and 10/11 become 01. Among the benefits of this fix: Zelda Wind Waker no longer crashes when you view the map. see http://forums.ngemu.com/dolphin-discussion/114035-those-pesky-bit-fields.html
