i965/fs: Fix can_propagate_from() source/destination overlap check.

The previous overlap condition only made sure that the VGRF numbers or
GRF-aligned offsets were different without taking the amount of data
written and read by the instruction into consideration.  Use the
regions_overlap() helper instead.
