getCALLSEQ_{END,START} to permit passing no DebugLoc
there.  UNDEF doesn't logically have DebugLoc; add
getUNDEF to encapsulate this.

A simple test program shows that debugging works. :-)

re-acquire the lock.

SelectionDAGISel::CreateScheduler, and make it just create the
scheduler. Leave running the scheduler to the higher-level code.
This makes the higher-level code a little more explicit and
easier to follow, and will help enable some future refactoring.

that previously included this header should include
SchedulerRegistry.h instead.

Add TargetInstrInfo::isSafeToMoveRegisterClassDefs. It returns true if it's safe to move an instruction which defines a value in the register class. Replace pre-splitting specific IgnoreRegisterClassBarriers with this new hook.

that used this header to select a scheduling policy should
use SchedulerRegistry.h instead (llvm-gcc and clang were
updated a while ago).

its corresponding getTargetNode.  Lots of

Refactor my previous change to maintain the distinction between AliasAnalysis and BasicAliasAnalysis.  This involves some wider changes because it
folds away some never-used methods.

Ignore dbg intrinsics while propagating conditional expression info. Take 2.

isAsCheapAsMove instructions can have register src operands. Check if they are really re-materializable.
This fixes sse.expandfft and sse.stepfft.

Machine LICM increases register pressure and it almost always increase code size. For now, disable it for optimizing for size.

ReMaterializeTrivialDef need to trim the live interval to the last kill if the copy kills the source register. This fixes uint64tof64.ll after ARM::MOVi is marked as isAsCheapAsAMove.

sure to print the value properly sext'd to the right pointer size.
This fixes PR3481.

between call frame setup/restore points.  Unfortunately, this regresses 
code size a bit, but at least it's correct now!
