what ConstantRange does for unsigned integers. Factor out a
common base class for common functionality.

Add some new functions for performing arithmetic on constant
ranges. Some of these are currently just stubbed out with
conservative implementations.

Add unittests for ConstantRange and ConstantSignedRange.

DAGTypeLegalizer::PromoteIntRes_EXTRACT_VECTOR_ELT take advantage of 
this new flexibility to simplify the code and make it deal with unusual 
vectors (like <4 x i1>) correctly.  Fixes PR3037.

-t is already used by gcc in the meaning 'ld -t' (trace). The Base plugin may
 want to emulate this behaviour.

Add some classes to produce pretty-printed asm.  We'll use these
shortly to provide nicely printed comments and other goodies in
asm files.

Add support for other GraphViz display tools.  This can help
with very large graphs, where dot isn't necessarily the 
most visually pleasing way of looking at the graph.
