62b9b6e38c Testcase for debug info from data-only files.
This one is x86-32-Darwin specific.

f71cb9b3ed Make debug info come out in data-only files.
This is a question of the debugging setup code not
being called at the right time, and it's called from
target-dependent code for some reason.  I have only
attempted to fix Darwin, but I'm pretty sure it's
broken elsewhere; I'll leave that to people who can
test it.

7ba11c552b Remove custom expansion from LegalizeTypes when doing
soft float: experiments show that targets aren't
expecting this for results or for operands.  Add
support select/select_cc result soft float and
correct operand soft float for these.

the name prefix when we change them from internal to external.  This allows bugpointing
of codegen miscompilations to work more reliably on Darwin.

8e5f2c6f65 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.

instruction selection, and improves memory locality.

95d110920e 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.

6d9cdd5617 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.
