Dan Gohman 0d1e9a8e04 Switch the MachineOperand accessors back to the short names like
isReg, etc., from isRegister, etc.

Owen Anderson 27fb3dcbc7 Make TargetInstrInfo::copyRegToReg return a bool indicating whether the copy requested
was inserted or not.  This allows bitcast in fast isel to properly handle the case
where an appropriate reg-to-reg copy is not available.

Owen Anderson 4f6bf04616 Convert uses of std::vector in TargetInstrInfo to SmallVector. This change had to be propoagated down into all the targets and up into all clients of this API.

Dan Gohman 3b46030375 Pool-allocation for MachineInstrs, MachineBasicBlocks, and
MachineMemOperands. The pools are owned by MachineFunctions.

This drastically reduces the number of calls to malloc/free made
during the "Emit" phase of scheduling, as well as later phases
in CodeGen. Combined with other changes, this speeds up the
"instruction selection" phase of CodeGen by 10% in some cases.

Evan Cheng 7d98a48f15 - Remove calls to copyKillDeadInfo which is an N^2 function. Instead, propagate kill / dead markers as new instructions are constructed in foldMemoryOperand, convertToThressAddress, etc.
- Also remove LiveVariables::instructionChanged, etc. Replace all calls with cheaper calls which update VarInfo kill list.

Evan Cheng 3b3286d4bc It's not always safe to fold movsd into xorpd, etc. Check the alignment of the load address first to make sure it's 16 byte aligned.

Owen Anderson 2a3be7bb6c Move even more functionality from MRegisterInfo into TargetInstrInfo.
Some day I'll get it all moved over...

Chris Lattner 25568e4cef Fix a problem where lib/Target/TargetInstrInfo.h would include and use
a header file from libcodegen.  This violates a layering order: codegen
depends on target, not the other way around.  The fix to this is to 
split TII into two classes, TII and TargetInstrInfoImpl, which defines
stuff that depends on libcodegen.  It is defined in libcodegen, where 
the base is not.

Owen Anderson 7a73ae9a86 Move copyRegToReg from MRegisterInfo to TargetInstrInfo. This is part of the
Machine-level API cleanup instigated by Chris.

Chris Lattner a5bb370aa4 Add new shorter predicates for testing machine operands for various types:
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.
