7439ef2aba Fix indenting, remove tabs. 
Learn from sext and zext. The destination value falls within the range of the
source type.

Generalize properties regarding constant ints.

Get smarter about marking blocks as unreachable. If 1 >= 2 in order for this
block to execute, then it isn't reachable.

3e01807e87 Fix a miscompilation in the addr mode code trying to implement X | C and 
X + C to promote LEA formation.  We would incorrectly apply it in some cases
(test) and miss it in others.

This fixes CodeGen/X86/2007-02-04-OrAddrMode.ll

15fb4ef992 switch the VRBaseMap in the scheduler from an std::map to a DenseMap. This 
speeds up the isel pass from 2.5570s to 2.4722s on kc++ (3.4%).

59d7c680b5 Introduce new UnarySDNode/BinarySDNode/TernarySDNode nodes, which coallocate 
their operands with the node itself.  This reduces malloc traffic for operand
lists.  This reduces isel time on kc++ from 2.6164 to 2.5570s, about 2.3%.
