Subject: [PATCH] gsdx: help stupid compiler to allow 32 byte move

Default copy-constructor is eight 32 bits move

GSRendererOGL::Lines2Sprites code shrinks from 510B to 398B
(loop of the function 296B => 181B). Hopefully it will reduce the cost
to convert line to sprite on the CPU (i.e. when geometry shader is disabled)
