|\ | | | | Switch from RelPtr to RelSlice

| * Move RelPtr/RelSlice out of arches into commonD. Shah2021-01-274-118/+42
| | | | | | | | | | | | | | The bba approach seems widely used enough that it's reasonable for this to become part of common code. Signed-off-by: D. Shah <dave@ds0.me>
| * ecp5: Switch from RelPtr to RelSliceD. Shah2021-01-273-165/+143
| | | | | | | | | | | | | | | | | | | | This replaces RelPtrs and a separate length field with a Rust-style slice containing both a pointer and a length; with bounds checking always enforced. Thus iterating over these structures is both cleaner and safer. Signed-off-by: D. Shah <dave@ds0.me>
