The ADD and ADDK (and all variants) instructions where flip-flopped in the MBlaze backend. This bug fix makes 64-bit math work on the MBlaze backend.

Implement ELF object file writing support for the MBlaze backend. Its not perfect yet, but it works for many tests.

2. Parsing .word directive in MBlaze asm parser
3. Fixing hack where memory instructions reversed order of last two parameters
4. Fixing many improperly encoded instructions
5. Support parsing special instructions (MFS,MTS,etc.)
6. Removing unused functions from inst printer

Major cleanup of whitespace and formatting issues in MBlaze backend

mostly based on the ARM AsmParser at this time and is not particularly
functional.

Changed the MBlaze data layout from:
    "E-p:32:32-i8:8:8-i16:16:16-i64:32:32-f64:32:32-v64:32:32-v128:32:32-n32"
to:
    "E-p:32:32:32-i8:8:8-i16:16:16"
because the MicroBlaze doesn't have i64, f64, v64, or v128 data types.

Cleaned up the MBlaze source code:
    1. The floating point register class has been removed. The
       MicroBlaze does not have floating point registers. Floating
       point values are simply stored in integer registers.
    2. Renaming the CPURegs register class to GPR to reflect the
       standard naming.
    3. Removing a lot of stale code from AsmPrinter after
       the conversion to InstPrinter.
    4. Simplified sign extended loads by marking them as
       expanded in ISelLowering.

    1. A delay slot filler that searches for valid instructions
       to fill the delay slot with. Previously NOPs would always
       be inserted into delay slots.
    2. Support for MC based instruction printer added.
    3. Support for MC based machine code generation and ELF
       file generation. ELF file generation does not yet
       completely work as much of the ELF support infrastructure
       is still x86/x86-64 specific.
    4. General clean up of the MBlaze backend code. Much of the
       tablegen code has been cleanup and simplified.

Bug Fixes:
    1. Removed duplicate periods from subtarget feature descriptions.
    2. Many of the instructions had bad machine code information
       in the tablegen files. Much of this has been fixed.

incarnations), integrated into the MC framework.  

The disassembler is table-driven, using a custom TableGen backend to 
generate hierarchical tables optimized for fast decode.  The disassembler 
consumes MemoryObjects and produces arrays of MCInsts, adhering to the 
abstract base class MCDisassembler (llvm/MC/MCDisassembler.h).

The disassembler is documented in detail in

- lib/Target/X86/Disassembler/X86Disassembler.cpp (disassembler runtime)
- utils/TableGen/DisassemblerEmitter.cpp (table emitter)

You can test the disassembler by running llvm-mc -disassemble for i386
or x86_64 targets.  Please let me know if you encounter any problems
with it.
