Nate Begeman 1196287522 Hard code CmpInst back to i1 for now while I go track down what in the bitcode reader/writer is assuming i1

Nate Begeman cfcb56091b Add support for vicmp/vfcmp codegen, more legalize support coming. 
This is necessary to unbreak the build.

Bill Wendling 70613b84da One real change - don't hoist something that's trivially rematerializable. It's 
possible for it to produce worse code than before.

The rest of this patch is code cleanup.

Ted Kremenek 92f78f4c04 When reading in the DeclCtx during deserialization, register the DeclCtx of the 
ScopedDecl with the backpatcher, and *not* a local variable on the stack. The
value of DeclCtx gets filled in *later* by the backpatcher.

This fixes: http://llvm.org/bugs/show_bug.cgi?id=2308

Chris Lattner 5287765d1a 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 ;-)

Chris Lattner 47fed61526 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.

Dan Gohman 3c0e11af64 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.
