Is it defined what DWARF unwind information looks like when made up of
bytes wider than 8 bits? Certainly GCC's code won't allow for it at
present.
The string handling code is a major area which doesn't allow for target
and host bytes being different. But everything target-independent
hardcoding integer modes wider than QImode is potentially wrong; with wide
bytes, many of those modes may not exist.
