[Mesa-dev] [PATCH 25/57] i965/fs: Stop using fs_reg::in_range() in favor of regions_overlap().

[Francisco Jerez]

Its only use left in the FS back-end should be using regions_overlap()
instead to avoid getting a false negative result in cases where source
and destination overlap but the former starts before the latter in the
VGRF file.
