register classes.

2af8a9f980 Watch out for the following case: 
1. Use expects a chain output.
2. Node is expanded into multiple target ops.
3. One of the inner node produces a chain, the outer most one doesn't.

3466555d87 When isel'ing a node, mark its operands "InFlight" before selecting them. These 
nodes should not be folded into other nodes.
This fixes the miscompilation of PR 749.

7ed816f900 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

some versions of nm don't recognize it (its a gnu option).

05e3e8fdc9 Don't require the "dot" program if -flat option is given, and don't produce 
any of the fancy graphs or other output. Just produce the flat, makefile
style output on stdout.
