```
std.debug.cpu_context: consider arm and aarch64 reserved register ranges unsupported

If these ever get allocated, it's most likely going to be for things that don't
matter to us anyway, so completely abandoning DWARF unwinding just because we
see these doesn't seem justified. We will still do so if we're actually asked to
read from such a register, which is the only actually problematic case; see
c23a5ccd19 for more details.
