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:

CC      fs/ocfs2/suballoc.o
fs/ocfs2/suballoc.c: In function 'ocfs2_reserve_suballoc_bits':
fs/ocfs2/suballoc.c:638: error: unrecognizable insn:

        (subreg:HI (reg:SI 149 macl) 2)) -1 (expr_list:REG_DEAD (reg:SI 149 macl)
        (nil)))
fs/ocfs2/suballoc.c:638: internal compiler error: in extract_insn, at recog.c:1991

This patch switches over to using an arbitrarily assigned register instead.

While the same issue does not exist in the SH-5 case, there is likewise no harm
in having an alternate register used for the byterev/shari pair.

sh64 has traditionally had this configurable via a Kconfig option
(CONFIG_SH64_USER_MISALIGNED_FIXUP). In practice it has never really been
terribly useful to turn this off, so just get rid of the option entirely.

We leave the sysctl around so we don't end up breaking existing root
file systems, and to allow folks that really want this off to do so at
their own risk.
