9d4209fb82 1. Add a pass to fold debug label instructions so a debug info client can detect
empty ranges.

2. Reorg how MachineDebugInfo maintains changes to debug labels.

3. Have dwarf writer use debug label info to simplify scopes and source line
coorespondence.

4. Revert the merging of compile units until I can get the bugs ironed out.

65c5d75bc8 Add a -disable-cbe-printf-a option so that the output of the C Backend
stands a chance of being compiled with a non C99 C compiler. The default
is enabled so you must specifically disable this feature if you want the
CBE output compiled with an older C compiler.

24446e253a Merging ISD::LOAD and ISD::LOADX. Added LoadSDNode to represent load nodes.
Chain and address ptr remains as operands. SrcValue, extending mode, extending
VT (or rather loaded VT before extension) are now instance variables of
LoadSDNode.

Introduce load / store addressing modes to represent pre- and post-indexed
load and store. Also added an additional operand offset that is only used in
post-indexed mode (i.e. base ptr += offset after load/store).

Added alignment info (not yet used) and isVolatile fields.

de65fb3a8b Now that ConstantBool::True/False are gone, we can modify Type.cpp to
eliminate its static dtors, without having code that depends on order of
initialization.  Eliminate static ctors/dtors from Type.cpp.

02569d7355 - Added a hook processFunctionBeforeCalleeSaveScn(). This is called by PEI just
before it determines which callee-save registers are to be spilled. This allows
the target to make changes such as forcing certain physical registers to be
spilled.
- Modified comments. It's important to note the order of registers in the array
returns by getCalleeSaveRegs() determines the order of callee save spill code.
