The X86 prefix changes LGTM if you want to commit that separately and leave this patch for just the arm guys to review

Thanks, i will commit the test/CodeGen/X86/extract-lowbits.ll part.

I'm honestly not sure about the test/CodeGen/*/extract-bits.ll,
we'd only need it if we want to actually let the BEXTR do the LSHR's work, too.
Or at least maybe the *_skipextrauses() tests aren't needed..

@lebedev.ri What happened with this patch? I can see x86/extract-lowbits.ll in trunk

Nothing much. I committed the interesting subset of tests, but the rest is stuck just as the D48491.
