I ran into a testcase regression with my new correct version. See PR 60669 for
that case.

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:

More missed optimistions (gcc version 4.9.2 20141101 (Red Hat 4.9.2-1) (GCC))
I see it using movbe for the pointer_abuse() function, but can't see a simple
way to make it use

Er, yes. Sorry, I originally tried it with uint16_t but it wasn't even using
movbe for the pointer_abuse() function then, so I made it 32-bit instead.
Badly. Come to think of it,

The original testcase in comment #0 is still not optimized at the gimple level
due to extra casts. If I use unsigned instead of int, the testcase is
optimized at the gimple level.
