Owen Anderson ddbe430732 Fix a misunderstanding of the algorithm. Really, we should be tracking values
and expression separately.  We can get around this, however, by only keeping
opaque values in TMP_GEN.

Owen Anderson 3c9d8eef21 Don't use std::set_difference when the two sets are sorted differently. Compute
the difference manually instead.

This allows GVNPRE to produce correct analysis for the example in the GVNPRE
paper.

Dan Gohman 92a7f3a65e Resolve implicit alignment before computing the FoldingSet information so
that the CSE map always contains explicit alignment information. This allows
more loads to be CSE'd when there is a mix of explicit-alignment loads and
implicit-alignment loads.

Also, in SelectionDAG::FindModifiedNodeSlot, add the operands to the
FoldingSetNodeID before the load/store information instead of after, so
that it matches what is done elsewhere.
