glamor: Don't abuse large_pixmap members for regular pixmaps 

glamor_compute_clipped_regions_ext wants to treat small and large
pixmaps uniformly and did that by writing into the large pixmap
union member in small pixmaps to construct something that looks like a
one texture large pixmap.

Instead of doing that, simply allocate the necessary elements locally
on the stack and use them from there.
