Chris Lattner 9c9bfb6870 per a suggestion by Frits van Bommel, mark all MBlaze Pseudo 
instructions as isCodeGenOnly in the parent class instead of
sprinkling it throughout the .td files.

Wesley Peck 078db00f1d Reverting the commit 116986. It was breaking the build on llvm-x86_64-linux though it 
compiles on OS X. I'll ensure that it builds on a linux machine before committing
again.

Wesley Peck f608ac4db9 Major update of the MicroBlaze backend. The new features are: 
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.

Wesley Peck e4801e49c9 Adding the MicroBlaze backend. 
The MicroBlaze is a highly configurable 32-bit soft-microprocessor for
use on Xilinx FPGAs. For more information see:
http://www.xilinx.com/tools/microblaze.htm
http://en.wikipedia.org/wiki/MicroBlaze

The current LLVM MicroBlaze backend generates assembly which can be
compiled using the an appropriate binutils assembler.
