Add some debug routines to SelectionDAG to dump full DAGs.
print/dumpWithDepth allows one to dump a DAG up to N levels deep.
dump/printWithFullDepth prints the whole DAG, subject to a depth limit
on 100 in the default case (to prevent infinite recursion).

Have CannotYetSelect to a dumpWithFullDepth so it is clearer exactly
what the non-matching DAG looks like.

improve portability to avoid conflicting with std::next in c++'0x.
Patch by Howard Hinnant!

Add edge source labels to SelectionDAG graphs, now that the graph printing
framework omits differentiated edge sources in the case where the labels
are empty strings.

Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used.
Note that "hasDotLocAndDotFile"-style debug info was already broken;
people wanting this functionality should implement it in the

Target-independent support for TargetFlags on BlockAddress operands,
and support for blockaddresses in x86-32 PIC mode.

Adjust isConstantSplat to allow for big-endian targets.
PPC is such a target; make it work.

Initial target-independent CodeGen support for BlockAddresses.

Move DataTypes.h to include/llvm/System, update all users. This breaks the last
direct inclusion edge from System to Support.

INTRINSIC_W_CHAIN and INTRINSIC_VOID do not use MemSDNode. They
may access memory, but they don't carry a MachineMemOperand.

Improve MachineMemOperand handling.
- Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions.
This eliminates MachineInstr's std::list member and allows the data to be
created by isel and live for the remainder of codegen, avoiding a lot of
copying and unnecessary translation. This also shrinks MemSDNode.
- Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated
fields for MachineMemOperands.
- Change MemSDNode to have a MachineMemOperand member instead of its own
fields with the same information. This introduces some redundancy, but
it's more consistent with what MachineInstr will eventually want.
- Ignore alignment when searching for redundant loads for CSE, but remember
the greatest alignment.

Target-specific code which previously used MemOperandSDNodes with generic
SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range
so that the SelectionDAG framework knows that MachineMemOperand information
is available.

Better solution for tracking both the original alignment of the access, and the current alignment based
on the source value offset. This avoids increasing the size of mem nodes.

Add an "original alignment" field to load and store nodes. This enables the
DAG Combiner to disambiguate chains for loads and stores of types which are
broken up by the Legalizer into smaller piece

Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well.

This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)

Split EVT into MVT and EVT, the former representing _just_ a primitive type, while
the latter is capable of representing either a primitive or an extended type.
