3e43cd4105 Fix handling of max and full set. 
A full set is a constant range that represents any number. If you take the
umax of that and [5, 10) you end up with [5, INT_MAX] because the values less
than 5 would be umax's against a value which is at least 5.

3ddde921ee make filecheck default to canonicalizing horizontal whitespace 
away.  This way you can write a space and it matches arbitrary spaces and tabs.

6bfeeb798a We get the P modifier wrong in a lot of cases, just add some more rigorous testing. 
In addition to fixing this, I still need to do some more testing on darwin.

268b47b1fb Major changes to Thumb (not Thumb2). Many 16-bit instructions either modifies CPSR when they are outside the IT blocks, or they can predicated when in Thumb2. Move the implicit def of CPSR to an optional def which defaults CPSR. This allows the 's' bit to be toggled dynamically. 
A side-effect of this change is asm printer is now using unified assembly. There are some minor clean ups and fixes as well.

fee40fdcd9 Move a method that creates constant ranges relative to another constant range 
per icmp predicate out of predsimplify and into ConstantRange.

Add another utility method that determines whether one range is a subset of
another. Combine with the former to determine whether icmp pred range, range
is known to be true or not.
