There is nothing in these routines that inherently depends on R0 use.
Given that these routines are inlined, it is rather easy to blow up the
compiler by exhausting the spill class when performing a 64-bit swab.

This presently manifests itself as the following:

sh64 has traditionally had this configurable via a Kconfig option
(CONFIG_SH64_USER_MISALIGNED_FIXUP). In practice it has never really been

their own risk.
