Rather than attach patches here, it would be better to link to the mailing
message where the patch was approved. Otherwise, it is not clear whether these
are tentative patches or approved patches.

And if the patch fixes a PR, it is better to link to the patch from the
original PR and add the PR to the list of bugs that this PR depend on (you can
use the alias "4.6" in the field "Bug X blocks" of your PR).

Most of the h8_enhancement patch has been applied.  Unfortunately, one aspect
of that change (reordering alternatives in the logical and, ior, xor patterns)
causes codesize & performance regressions and has not been installed.  The
fundamental problem is the bit insns do not set cc0 and as a result we often
miss opportunities to remove tst insns.

I'm withdrawing the color.patch2.  While the patch makes sense in theory and
seems to help x86, it's causing clear regressions on other targets such as the
mn103.  I've been unable to resolve the regressions without making the patch
basically worthless on x86.  At this point I just don't see that it's worth the
effort.
