96135b617a This patch cleans up the ProfileInfo by 
*) introducing new data type and export function of edge info for whole function (preparation for next patch).
*) renaming variables to make clear distinction between data and containers that contain this data.
*) updated comments and whitespaces.
*) made ProfileInfo::MissingValue a double (as it should be...).

(Discussed at http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20090817/084955.html.)

3d01334e6f Fix a bug in the over-index constant folding. When over-indexing an 
array member of a struct, it's possible to land in an arbitrary position
inside that struct, such that attempting to find further getelementptr
indices will fail. In such cases, folding cannot be done.

de0e587e63 Canonicalize indices in a constantexpr GEP. If Indices exceed the 
static extents of the static array type, it causes GlobalOpt and
other passes to be more conservative. This canonicalization also
allows the constant folder to add "inbounds" to GEPs.

   missing information.

699db99c1a 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).

a1b78d133e Restrict LDA to GEPs with the same pointer offset.

fef8bb24de Instead of eagerly creating new SCEVs to replace all SCEVs that are 
affected after a PHI node has been analyzed, just remove affected
SCEVs from the Scalars map, so that they'll be (lazily) recreated as
needed. This avoids creating SCEV objects that aren't actually needed.

Also, rewrite the associated def-use walking code to be non-recursive
and to continue traversing past Instructions that don't have an
entry in the Scalars map.

ce63ffb52f More migration to raw_ostream, the water has dried up around the iostream hole. 
- Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

   the old style.
