2904538fc3 Simplify erase_one slightly. It's not necessary to preserve
the value of the element to be erased while the heap is
being updated.

55e283c71e Revamp the loop unroller, extending it to correctly update PHI nodes
in the presence of out-of-loop users of in-loop values and the trip
count is not a known multiple of the unroll count, and to be a bit
simpler overall. This fixes PR2253.

8cb8245cf1 Move a DenseMap's declaration outside of a loop, and just call
clear() on each iteration. This avoids allocating and deallocating
all of DenseMap's memory on each iteration.

963a97f1a3 Fix PR2369 by making scalarrepl more careful about promoting
structures.  Its default threshold is to promote things that are
smaller than 128 bytes, which is sane.  However, it is not sane
to do this for things that turn into 128 *registers*.  Add a cap
on the number of registers introduced, defaulting to 128/4=32.

69bfb15ecd Make custom lowering of ADD work correctly. This
fixes PR2476; patch by Richard Osborne.  The same
problem exists for a bunch of other operators, but
I'm ignoring this because they will be automagically
fixed when the new LegalizeTypes infrastructure lands,
since it already solves this problem centrally.
