22d94da65b Clean up a bunch of caching stuff in memdep. This reduces the time to run GVN 
on 403.gcc from ~15s to ~10s.

a5a692b9bb Switch the internal "Info" map from an std::map to a DenseMap. This 
speeds up idom by about 45% and postidom by about 33%.

Some extra precautions must be taken not to invalidate densemap iterators.

5912537997 switch the DomTreeNodes and IDoms maps in idom/postidom to a 
DenseMap instead of an std::map.  This speeds up postdomtree
by about 25% and domtree by about 23%.  It also speeds up clients,
for example, domfrontier by 11%, mem2reg by 4% and ADCE by 6%.

bb705e230a Rename ScalarEvolution::deleteInstructionFromRecords to

838ba27094 Add a SCEV class and supporting code for sign-extend expressions. 
This created an ambiguity for expandInTy to decide when to use
sign-extension or zero-extension, but it turns out that most of its callers
don't actually need a type conversion, now that LLVM types don't have
explicit signedness. Drop expandInTy in favor of plain expand, and change
the few places that actually need a type conversion to do it themselves.

e5e2e8d917 Change the callgraph representation to store the callsite along with the 
target CG node.  This allows the inliner to properly update the callgraph
when using the pruning inliner.  The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.

This fixes PR827 and Transforms/Inline/2006-07-12-InlinePruneCGUpdate.ll

the memory usage for the testcase in PR681 from 496 to 26MB of ram on my
darwin system, and reduces the runtime from 32.8 to 0.8 seconds on a
2.5GHz G5.  This also enables future code sharing between Dom and PostDom
now that they share near-identical implementations.
