To catch bugs like the one fixed in
http://llvm.org/viewvc/llvm-project?view=rev&revision=78127, I'm changing the
ExecutionEngine's global mappings to hold AssertingVH<const GlobalValue>. That
way, if unregistering a mapping fails to actually unregister it, we'll get an
assert. Running the jit nightly tests didn't uncover any actual instances of
the problem.

This also uncovered the fact that AssertingVH<const X> didn't work, so I fixed
that too.

SIV/MIV classification for LDA.

LoopDependenceAnalysis::getLoops is currently O(N*M) for a loop-nest of
depth N and a compound SCEV of M atomic SCEVs. As both N and M will
typically be very small, this should not be a problem. If it turns out
to be one, rewriting getLoops as SCEVVisitor will reduce complexity to
O(M).
