266e42b312 For PR950: 
This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

79a42ac941 Switch over Transforms/Scalar to use the STATISTIC macro. For each statistic 
converted, we lose a static initializer.  This also allows GCC to emit warnings
about unused statistics.

edcc8c2f8b Remove the 'printname' argument to WriteAsOperand. It is always true, and 
passing false would make the asmprinter fail anyway.

7e80b0b31e For PR950: 
Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

e0fc4dfc22 For PR950: 
This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

b5e381a8cf Fix a problem that Dan Berlin noticed, where reassociation would not succeed 
in building maximal expressions before simplifying them.  In particular, i
cases like this:

X-(A+B+X)

the code would consider A+B+X to be a maximal expression (not understanding
that the single use '-' would be turned into a + later), simplify it (a noop)
then later get simplified again.

Each of these simplify steps is where the cost of reassociation comes from,
so this patch should speed up the already fast pass a bit.

Thanks to Dan for noticing this!

9f284e0a3c Fix PR557 and basictest[34].ll. 
This makes reassociate realize that loads should be treated as unmovable, and
gives distinct ranks to distinct values defined in the same basic block, allowing
reassociate to do its thing.

1e5065052a Rewrite the guts of the reassociate pass to be more efficient and logical. Instead 
of trying to do local reassociation tweaks at each level, only process an expression
tree once (at its root).  This does not improve the reassociation pass in any real way.
