ab7d9ccf18 Add a new SparsePropagation analysis utility, which allows you to do 
SCCP like sparse lattice analysis with relative ease.  Just pick your
lattice function and implement the transfer function and you're good.
Just make sure you don't break monotonicity ;-)

5c8e8d7fc5 Fix various DOUTs to not call the extremely expensive Value::getName() 
method.  DOUT statements are disabled when assertions are off, but the
side effects of getName() are still evaluated.  Just call getNameSTart,
which is close enough and doesn't cause heap traffic.

9018e836fe For now, abort when an ISD::VAARG is encountered on x86-64, rather 
than silently generate invalid code.

llvm-gcc does not currently use VAArgInst; it lowers va_arg in the
front-end.
