Bill Wendling 00f0cddfd4 We need to pass the TargetMachine object to the InstPrinter if we are printing
the alias of an InstAlias instead of the thing being aliased. Because we need to
know the features that are valid for an InstAlias.

This is part of a work-in-progress.

Wesley Peck f4efd582ad Make it a little bit more explicit that the MBlaze backend only supports upto
32-bit immediate values.

Wesley Peck 078db00f1d Reverting the commit 116986. It was breaking the build on llvm-x86_64-linux though it
compiles on OS X. I'll ensure that it builds on a linux machine before committing
again.

Wesley Peck f608ac4db9 Major update of the MicroBlaze backend. The new features are:
1. A delay slot filler that searches for valid instructions
       to fill the delay slot with. Previously NOPs would always
       be inserted into delay slots.
    2. Support for MC based instruction printer added.
    3. Support for MC based machine code generation and ELF
       file generation. ELF file generation does not yet
       completely work as much of the ELF support infrastructure
       is still x86/x86-64 specific.
    4. General clean up of the MBlaze backend code. Much of the
       tablegen code has been cleanup and simplified.

Bug Fixes:
    1. Removed duplicate periods from subtarget feature descriptions.
    2. Many of the instructions had bad machine code information
       in the tablegen files. Much of this has been fixed.
