1. Change MBlaze indirect branches to use absolute branch BRALD instead of pc relative branch BRLD.
...
2. Make sure that the MBlaze stack is aligned to 4-byte boundaries.
3. Determine frame indexes that should be placed in the callers stack frame, as per the MBlaze ABI, and place them in the correct locations.

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.

The MicroBlaze is a highly configurable 32-bit soft-microprocessor for
use on Xilinx FPGAs. For more information see:

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