useful right now when we only do local scheduling.

Destroy live-variable information after scheduling so it is
recomputed before later phases (e.g., reg. allocation).
Use deterministic iterator to enumerate sched graphs.

Also re-enable instr. scheduling pass.

Improve checking for constants in Multiply.
Simpler method to keep track of when a node is folded into its parent.
Several other bug fixes.

llvm-svn: 1964

Also, add a flag to marked nodes that do not need code because they
have been folded into the user (parent in the BURG tree).

Also moved to the Scalar/ directory and renamed to "MultiDim".

* AllocationInst now always has an array size operand

llvm-svn: 1939

* Move AllocationInst ctor to iMemory.cpp
* AllocationInst's always have one operand, even if it is a uint 1
