e8639036b1 it's more elegant to put the "getConstantPool" and
"getFixedStack" on the MachinePointerInfo class.  While
this isn't the problem I'm setting out to solve, it is the
right way to eliminate PseudoSourceValue, so lets go with it.

93a95ae8a9 force clients of MachineFunction::getMachineMemOperand to provide a
MachinePointerInfo, propagating the type out a level of API.  Remove
the old MachineFunction::getMachineMemOperand impl.

da39c39644 start pushing MachinePointerInfo out through the MachineMemOperand interface
to the MachineFunction construction methods.

e8e2e80f40 refactor the Value*/offset pair from MachineMemOperand out to a new
MachinePointerInfo struct, no functionality change.

This also adds an assert to MachineMemOperand::MachineMemOperand
that verifies that the Value* is either null or is an IR pointer type.

0c8ae782cb Make a few more LLVM headers parsable as standalone headers.
Fix some problems with the hidden copy constructors for
ImmutableMap/ImmutableSet found by Clang++.

c76909abfe 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.

cd26ec5f3c Give MachineMemOperand an operator<<, factoring out code from
two different places for printing MachineMemOperands.

Drop the virtual from Value::dump and instead give Value a
protected virtual hook that can be overridden by subclasses
to implement custom printing. This lets printing be more
consistent, and simplifies printing of PseudoSourceValue
values.

28f02fdd76 Change MachineMemOperand's alignment value to be the alignment of
the base pointer, without the offset. This matches MemSDNode's
new alignment behavior, and holds more interesting information.

obtained via accessor functions.

review feedback from Chris quite a while ago. No functionality
change.
