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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96969 91177308-0d34-0410-b5e6-96231b3b80d8
