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".

class. The Method class is obsolete (renamed) and all references to it
are being converted over to Function.

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.

(b) any instructions that use or set CC registers. Whether or not the
latter are needed really should be machine-dependent.

(1) Add edges for Values that are written by multiple m/c instructions
(2) Add edges for LLVM operands that are not machine operands (e.g., Call args)

Move files from lib/CodeGen/TargetMachine to lib/Target
Move TargetData.h and TargetMachine.h to Target/{Data.h|Machine.h}
Prepare to split TargetMachine.h into several smaller files
