Define a maximum supported alignment value for load, store, and
...
alloca instructions (constrained by their internal encoding),
and add error checking for it. Fix an instcombine bug which
generated huge alignment values (null is infinitely aligned).
This fixes undefined behavior noticed by John Regehr.

After updating value handles for RAUW, check that no weak or tracking handles
...
are still on the list. This might happen if a CallbackVH created some new value
handles for the old value when doing RAUW. Barf if it occurs, since it is almost
certainly a mistake.

Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock:
...
don't visit all blocks in the function, and don't iterate over the split blocks'
predecessor lists for each block visited.
Also, remove the special-case test for the entry block. Splitting the entry
block isn't common enough to make this worthwhile.
This fixes a major compile-time bottleneck which is exposed now that
LoopSimplify isn't being redundantly run both before and after
DominanceFrontier.
