i965/fs: Simplify and improve accuracy of compute_to_mrf() by using regions_overlap().

Compute-to-mrf was being rather heavy-handed about checking whether
instruction source or destination regions interfere with the copy
instruction, which could conceivably lead to program miscompilation.
Fix it by using regions_overlap() instead of the open-coded and
dubiously correct overlap checks.
