the MCCodeEmitter, which seems like a better organization.

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.

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.
