Bob Wilson ce51f782dd Check if function names start with "llvm." before trying to lookup them up as 
intrinsics.  The intrinsic lookup code assumes that this check has been done
and assumes the names are at least 6 characters long.  Valgrind complained
about this.  pr6638.

Wesley Peck 05d9124625 Adding function "lookupGCCName" to MBlazeIntrinsicInfo 
Adding the function "lookupGCCName" to the MBlazeIntrinsicInfo
class to support the Clang MicroBlaze target.

Additionally, minor fixes which remove some unused PIC code 
(PIC is not supported yet in the MicroBlaze backend) and
removed some unused variables.

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.
