5b43af962b 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!

e64574ce71 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.

c352d2c530 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.

d0d79c01b4 Allow combinations of True/Anti/Output flags for each edge to
support, e.g., dependences on Call instructions.

f43e3366ef 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.

Renamed some header files.

46cbff625e Chris seems fond of #include <vector>. Fix these. Also convert use list in
Value to a vector instead of a list.

Move SchedGraph.h & SchedPriorities.h into lib/CodeGen/InstrScheduling
