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

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

but did not pass the arguments by reference!
Also added a function to get a register class by ID.

Also, use distinct names for the three types of SetMachineOperand to
avoid painful overloading problems and errors.
Bug fix in converting-int-to-float. Other minor stuff.

wrong register class for saving CC registers.
Also, use distinct names for the three types of SetMachineOperand.

Different labels were generated for the same name in different passes.
Use an annotation to hold a fixed table of names.

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
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1750 91177308-0d34-0410-b5e6-96231b3b80d8
Method::inst_* is now in llvm/Support/InstIterator.h
GraphTraits specializations for BasicBlock and Methods are now in llvm/Support/CFG.h

function in the one .cpp file that uses it. Use ValueSet's instead.
* Prepare to delete LiveVarSet.h & LiveVarSet.cpp
* Eliminate the ValueSet class, making all old member functions into global
templates that will eventually be moved to Support.
* Eliminate some irrelevant const's

* applyFlowFunc DOES NOT NEED TO COPY the huge BB->BBLiveVar Map every time it is invoked!
* Big cleanups.
* Make BBLiveVar.h effectively an internal header file
* Prepare LiveVarMap.h for deletion

* InstructionScheduling is now a real pass
* InstrSched _uses_ LiveVar analysis, instead of creating it's own copy many times
through a loop. In this was LiveVarAnalysis is actually even SHARED by Register
allocation.
* SchedPriorities is now passed the live var information in
