Adding disassembler to the MicroBlaze backend.2010-10-27T00:23:01ZWesley Peckpeckw@wesleypeck.com2010-10-27T00:23:01Zurn:sha1:a06038369b830bb83742b6b39775f39dd9e69ae2

Adding initial AsmParser implementation for the MBlaze backend. It is2010-10-21T19:48:38ZWesley Peckpeckw@wesleypeck.com2010-10-21T19:48:38Zurn:sha1:4da992aebada7445ef68a7b6b94676dd26e9d537
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.

Reverting the commit 116986. It was breaking the build on llvm-x86_64-linux though it2010-10-21T03:34:22ZWesley Peckpeckw@wesleypeck.com2010-10-21T03:34:22Zurn:sha1:60e7127e862e359eb1b4694e5161da6dc4c2c397
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:2010-10-21T03:09:55ZWesley Peckpeckw@wesleypeck.com2010-10-21T03:09:55Zurn:sha1:13a949071ce2c887ae81db9f6880a660ff33a76d
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.
