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.

Dan Gohman 7f8b6d5f80 Pool-allocation for SDNodes. The pool is allocated once for each function, 
and reused across SelectionDAGs.

This drastically reduces the number of calls to malloc/free made during
instruction selection, and improves memory locality.

Dan Gohman e5932e5a3d Add some basic Pool-allocation infrastructure. This adds a Recycler class, 
for handling bookkeeping for deleted objects, as well as the alist class
template, for keeping lists of objects allocated from Recyclers, and some
related utilities.

Evan Cheng 4a898c0b11 TargetRegisterDesc::Name field is the same as the abstract register name. There is no need for targets to specify register names in addition to their AsmName's.

Bill Wendling b46e5165bf Use the canonical way to get an empty structure.

Dan Gohman d6ec05077f Refactor the tablegen DAGISelEmitter code for outputing calls to 
getTargetNode and SelectNodeTo to reduce duplication, and to
make some of the getTargetNode code available to SelectNodeTo.
Use SelectNodeTo instead of getTargetNode in several new
interesting cases, as it mutates nodes in place instead of
creating new ones.

This triggers some scheduling behavior differences due to nodes
being presented to the scheduler in a different order. Some of the
arbitrary scheduling decisions it makes are now arbitrarily made
differently. This is visible in CodeGen/PowerPC/LargeAbsoluteAddr.ll,
where a trivial scheduling difference led to a trivial register
allocation difference.

Dan Gohman 9169763955 Fix SDNode::MorphNodeTo (a function used by by SelectNodeTo) to 
properly track dead nodes that are on the original SDNode's operand
list but not the new one, and have no other uses.

Evan Cheng 03001cb820 Fix two serious LSR bugs. 
1. LSR runOnLoop is always returning false regardless if any transformation is made.
2. AddUsersIfInteresting can create new instructions that are added to DeadInsts. But there is a later early exit which prevents them from being freed.

Dan Gohman 768f2c9246 Remove most of the uses of SDOperandPtr, usually replacing it with a 
simple const SDOperand*, which is what's usually needed.

For AddNodeIDOperands, which is small, just duplicate the function to
accept an SDUse*.

For SelectionDAG::getNode - Add an overload that accepts SDUse* that
copies the operands into a temporary SDOperand array, but also has
special-case checks for 0 through 3 operands to avoid the copy in
the common cases.
