When we are in the label cc_dword_align, registers %o0 and %o1 have the same last 2 bits,
but it's not guaranteed one of them is zero. So we can get unaligned memory access
in label ccte. Example of parameters which lead to this:
%o0=0x7ff183e9, %o1=0x8e709e7d, %g1=3
With the parameters I had a memory corruption, when the additional 5 bytes were rewritten.
This patch corrects the error.
One comment to the patch. We don't care about the third bit in %o1, because cc_end_cruft
stores word or less.
