For 3, every load and store that is relative can be checked to be within the expected memory that is passed into the ELF. Dynamic load and stores can do a runtime check against available memory, these will be slow and should be avoided.
For 4, Statically linked PIC ELF with just a signle RX segment. Effectively we are linking a shared object with `-fpic -target bpf` and a linker script to collect everything into a single RX segment. Writable globals are not supported at the moment.
