849dcd928a Apply a patch from Nathan Keynes, which speeds up llvm-link on
the testcases in PR1860 from taking more than 1 hour (when I killed it)
to taking 1s.

bc1c82a0f7 Simplify ResolveTypes by pulling the null case out into the one
client that cares and simplifying its control flow.

Remove the DestST argument to ResolveTypes and RecursiveResolveTypes*
which are dead now.

inserting extractvalues. In particular, this prevents the insertion of
extractvalues that can't be folded away later. Also add an example of when this
stuff is needed.

b23d5adbc8 Move FindScalarValue from InstructionCombining.cpp to ValueTracking.cpp. While
I'm at it, rename it to FindInsertedValue.

The only functional change is that newly created instructions are no longer
added to instcombine's worklist, but that is not really necessary anyway (and
I'll commit some improvements next that will completely remove the need).

ad205a7687 Allow these transforms for types like i256 while
still excluding types like i1 (not byte sized)
and i120 (loading an i120 requires loading an i64,
an i32, an i16 and an i8, which is expensive).

8a08769bad Fix PR2434. When scanning for exising binary operator to reuse don't
take into account the instrucion pointed by InsertPt. Thanks to it, 
returning the new value of InsertPt to the InsertBinop() caller can be 
avoided. The bug was, actually, in visitAddRecExpr() method which wasn't 
correctly handling changes of InsertPt. There shouldn't be any 
performance regression, as -gvn pass (run after -indvars) removes any 
redundant binops.
