-Replace DebugLocTuple's Source ID with CompileUnit's GlobalVariable*
-Remove DwarfWriter::getOrCreateSourceID
-Make necessary changes for the above (fix callsites, etc.)

998e125a87 Move duplicated AddLiveIn function from X86 and ARM backends to be a method 
in the MachineFunction class, renaming it to addLiveIn for consistency with
the same method in MachineBasicBlock.  Thanks for Anton for suggesting this.

76d3838454 Reapply r66415, which was reverted in r66426 for 
causing a bootstrap failure.  Bootstraps here on
x86-32-linux and x86-64-linux.  Requested by the
author Gabor Greif who says that a bug that might
have been causing the failure has since been fixed.

c23b8719ef Give sentinel traits the right to determine the policy where the sentinel is kept. 
This should result in less indirect memory accesses, less dead writes and tighter code.

c7f6b8c5d4 "Ghostify" embedded sentinels. This is a real win in all cases 
because less bytes are allocated and subobject construction is gone.
For reference how it works, see BasicBlock.h.
Btw. it is very assuring to see that somebody has invented
this ilist-embedded sentinel technique before me :-)

fed90b6d09 Fold the useful features of alist and alist_node into ilist, and 
a new ilist_node class, and remove them. Unlike alist_node,
ilist_node doesn't attempt to manage storage itself, so it avoids
the associated problems, including being opaque in gdb.

Adjust the Recycler class so that it doesn't depend on alist_node.
Also, change it to use explicit Size and Align parameters, allowing
it to work when the largest-sized node doesn't have the greatest
alignment requirement.

Change MachineInstr's MachineMemOperand list from a pool-backed
alist to a std::list for now.

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.

84bc5427d6 Rename SSARegMap -> MachineRegisterInfo in keeping with the idea 
that "machine" classes are used to represent the current state of
the code being compiled.  Given this expanded name, we can start 
moving other stuff into it.  For now, move the UsedPhysRegs and
LiveIn/LoveOuts vectors from MachineFunction into it.

Update all the clients to match.

This also reduces some needless #includes, such as MachineModuleInfo
from MachineFunction.

PIC, and less dense forms of jump tables.

ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

1617e6c997 SSARegMap -- the mapping between SSARegisters and their RegisterClasses, which 
imply types of SSA Registers. This is on a per-function basis, so the
MachineFunction contains the SSARegMap, and has accessor functions to it.

7b3640bd12 Optional args are no longer allocated as they are discovered.

Also, ensure automatic vars and reg. spills areas are not extended
if their sizes are used for computing some other offset.
