Add an override to StringRef::getAsInteger which parses into an APInt.
...
It gets its own implementation totally divorced from the (presumably
performance-sensitive) routines which parse into a uint64_t.
Add APInt::operator|=(uint64_t), which is situationally much better than
using a full APInt.

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.
