So the original testcase shows there are missing other bitop related
optimizations on the tree level and conversions.
I have two patches which fix the original issue.
The first patch also fixes:

This patch is against svn r280157.

It is still okay in ppc-round.c.048t.local-fnsummary2 but it is wrong
