c10238de8c ice40: Switch from RelPtr to RelSlice 
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.

325d46e284 ice40/chipdb: Add wires to global network for all cells that can drive it 
The icebox DB is a bit inconsistent in how global network connections
are represented. Here we make it appear consistent by creating ports
on the cells that can drive it.
