321a813c53 Use do+while instead of while for loops which obviously have a
non-zero trip count. Use SmallVector's pop_back_val().

f012705c7e Avoid going through the LLVMContext for type equality where it's safe to dereference the type pointer.

25f2a23b4a split and/or/xor out into one overly-large (2000LOC) file. However, I think
it does make sense to keep them together, at least for now.

dramatic overkill for what the xform needed.

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.
