[LLVMdev] Cell SPU backend status

[Scott Michel]

It's official: Aerospace has given me permission to release the code,  
such as it is. I will be checking in pieces as I fix 80-col  
violations and performing general cleanups.

PLEASE NOTE: I intended to check the code into the LLVM SVN  
repository when the backend could generate a clean compile of llvm- 
gcc-4.2, but due to a bug, I'm going to have to check in __broken__  
code.

That said,  some caveats:

- I know the code can be cleaned up.
- I know the code isn't complete. Things that need work:
   - Branches, branch prediction instructions
   - Double FP
   - Intrinsics
- Test cases need fixing (will be checking those in incrementally)

OTOH, it's a start of something that will be a benefit to the LLVM  
community-at-large.
