A single MachineInstr operand may now be both a def and a use,
...
so additional dep. edges have to be added.
This was needed to correctly handle conditional move instructions!
MachineCodeForBasicBlock is now an annotation on BasicBlock.
Renamed "earliestForNode" to "earliestReadyTimeForNode".

Use deterministic iterator for SchedGraphs. This is actually not
...
useful right now when we only do local scheduling.

* Pull BasicBlock::pred_* and BasicBlock::succ_* out of BasicBlock.h and into
...
llvm/Support/CFG.h
* Make pred & succ iterators for intervals global functions
* Add #includes that are now neccesary because BasicBlock.h doesn't include
InstrTypes.h anymore

Create a new #include "Support/..." directory structure to move things

from "llvm/Support/..." that are not llvm dependant.
Move files and fix #includes

Eliminate most uses of the machine instruction vector for each LLVM instr,
...
since some m. instr. may be generated by LLVM instrs. in other blocks.
Handle non-SSA (anti and output) edges and true edges uniformly by
working with machine instructions alone.

Major improvement to how nodes are built for a BB.
...
LLVM instruction is no longer recorded in each node, but BB is.

Only add true dep. edges from an earlier to a later instruction.
...
This wasn't a problem until we started putting copies for Phi values
that produced cycles in the SchedGraph!

Major change to how defs are found when adding dependences (they
...
are now found as part of the initial walk of the machine code).
Also memory load/store instructions can be generated for non-memory
LLVM instructions, which wasn't handled before. It is now.

Modified graph construction to use one pass to find all defs.
...
Avoids having to handle some special cases that cause complex interactions
with instr. selection.

Separate VM instruction that generates the instructions that compute a value
...
from the value itself (the one causing an edge) because the latter may be
a temporary used within the instruction sequence for the VM instruction.

Value to a vector instead of a list.
