merge the new functionality and unittests into ConstantRange. Thanks to
Nick Lewycky for pointing out that it isn't necessary to have two separate
classes here.

Initial support for load / store multiple opt pass Thumb2 support (post-allocation only). It's kind of there, but not quite. I'll return to this later.

is modified. Otherwise, the unwinder will get confused. The old code (before I
started my hacking) did this. It dropped on the floor, because I wasn't aware of
this requirement.

On the plus side, if we use "alloca" in a function, we create frame pointers
even with -fomit-frame-pointer is enabled!

This is a Good Thing(tm)!!!

Fix ldrd / strd address mode matching code. It allows for +/- 8 bit offset. Also change the printer to make the scale 4 explicit.

Note, we are not yet generating these instructions.

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.

value.  Adjust other code to deal with that correctly.  Make 
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.

ImmutableSet/ImmutableMap: Allow caching of null digests by properly using a flag to record if the digest of an ImutAVLTree has been cached.

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

Regenerate for GraphViz tool discovery.

llvm-svn: 75145

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.
