2. Parsing .word directive in MBlaze asm parser
3. Fixing hack where memory instructions reversed order of last two parameters
4. Fixing many improperly encoded instructions
5. Support parsing special instructions (MFS,MTS,etc.)
6. Removing unused functions from inst printer

mostly based on the ARM AsmParser at this time and is not particularly
functional.
Changed the MBlaze data layout from:
"E-p:32:32-i8:8:8-i16:16:16-i64:32:32-f64:32:32-v64:32:32-v128:32:32-n32"
to:
"E-p:32:32:32-i8:8:8-i16:16:16"
because the MicroBlaze doesn't have i64, f64, v64, or v128 data types.
Cleaned up the MBlaze source code:
1. The floating point register class has been removed. The
MicroBlaze does not have floating point registers. Floating
point values are simply stored in integer registers.
2. Renaming the CPURegs register class to GPR to reflect the
standard naming.
3. Removing a lot of stale code from AsmPrinter after
the conversion to InstPrinter.
4. Simplified sign extended loads by marking them as
expanded in ISelLowering.
