EFI images start with a header page and then _text, so the load
address should use 'ImageBase' instead of _text. Just add the
ImageBase symbol to the non-efi build too and then change show_regs()
to use it instead. While there, add a couple convenience calculations
for the PC and return address (pre-subtract the load address from
them) in order to make it quicker for looking them up in an objdump.
