32c0cf5af9 inline the 'AddRHS' transformation, simplifying things significantly.
Eliminate the 'AddMaskingAnd' transformation, it is redundant with this
more general code right below it:
  // A+B --> A|B iff A and B have no bits set in common.

d0db8e8bad remove massive over-genality manifested as a big template
that got instantiated.  There is no reason for instcombine
to try this hard for simple associative optimizations.  Next
up, eliminate the template completely.

d7f5a58890 Truncate GEP indexes larger than the pointer size down to pointer size
when doing this transform if the GEP is not inbounds.  No testcase because
it is very difficult to trigger this: instcombine already canonicalizes
GEP indices to pointer size, so it relies specific permutations of the
instcombine worklist.

Thanks to Duncan for pointing this possible problem out.
