Consolidated use of BumpPtrAllocator shared by various ImmutableSet/ImmutableMap
...
factories.
Fixed a horrible bug in lval:DeclVar::classof(RValue* V); we weren't checking
V was an LValue, allowing nonlval::ConcereteInts to match isa<lval::DeclVar>.

The factories for ImutAVLTree/ImmutableSet/ImmutableMap now take an (optional)
...
BumpPtrAllocator argument to their constructors. This BumpPtrAllocator
will be used to allocate trees. If no BumpPtrAllocator is provided, one
is created (as before).

After yesterday's discussion ( http://lists.cs.uiuc.edu/pipermail/cfe-dev/2008-February/001044.html ), decided not to change the semantics of Type::isIncompleteType().
...
This commit simply changes a couple comments to reflect this decision.

If the LHS of the comparison is a loop-invariant we also want to move it
...
to the RHS. This simple change allows to compute loop iteration count
for loops with condition similar to the one in the testcase (which seems
to be quite common).

Added "Profile" method to APFloat for use with FoldingSet.
...
Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary
objects to a profile via dispatch to FoldingSetTrait<T>::Profile().
Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their
functionality is now replaced using the above mentioned member template.

Fix PR1798 - an error in the evaluation of SCEVAddRecExpr at an
...
arbitrary iteration.
The patch:
1) changes SCEVSDivExpr into SCEVUDivExpr,
2) replaces PartialFact() function with BinomialCoefficient(); the
computations (essentially, the division) in BinomialCoefficient() are
performed with the apprioprate bitwidth necessary to avoid overflow;
unsigned division is used instead of the signed one.
Computations in BinomialCoefficient() require support from the code
generator for APInts. Currently, we use a hack rounding up the
neccessary bitwidth to the nearest power of 2. The hack is easy to turn
off in future.
One remaining issue: we assume the divisor of the binomial coefficient
formula can be computed accurately using 16 bits. It means we can handle
AddRecs of length up to 9. In future, we should use APInts to evaluate
the divisor.
Thanks to Nicholas for cooperation!

Various updates from Sam Bishop:
...
"I have been working my way through the JIT and Kaleidoscope tutorials in my
(minuscule) spare time. Thanks again for writing them! I have attached a
patch containing some minor changes, ranging from spelling and grammar fixes
to adding a "Next: <next tutorial section>" hyperlink to the bottom of each
page.
Every page has been given the "next link" treatment, but otherwise I'm only
half way through the Kaleidoscope tutorial. I will send a follow-on patch
if time permits."
