Andrii Nakryiko 41cf0e3cba dwarf_loader: Don't recode enums and use real enum size in calculations 
This patch disables bitfield recoding logic in DWARF loader.
This logic is already disabled during DWARF->BTF conversion and without
it pahole reliably produces correct BTF bitfield offsets.

If this functionality is enabled, we are losing correct enum size
information. So let's disable and probably eventually remove it altogether.
