* Make pred & succ iterators for intervals global functions
* Add #includes that are now neccesary because BasicBlock.h doesn't include
InstrTypes.h anymore

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.

This wasn't a problem until we started putting copies for Phi values
that produced cycles in the SchedGraph!

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.

Avoids having to handle some special cases that cause complex interactions
with instr. selection.

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