[PATCH] 64-bit code generation for SPARC v9

[Jakob Stoklund Olesen]

Hi,

Please review these patches which add basic support for 64-bit code generation on SPARC v9.

I am sorry for sending a batch of patches, they've been piling up while I made some required changes to TableGen. Now that TableGen is ready, I'll switch to incremental commits for the remaining 64-bit work.

The SPARC v9 64-bit extension uses the same ALU instructions for i32 and i64 values. This caused some TableGen hiccups, and I didn't want to duplicate the entire instruction set just to work around TableGen's deficiencies.

The 64-bit support is not complete yet, in particular the 64-bit ABI needs some work both in the clang frontend and in the backend. Support for spilling,  64-bit stack frames, and the biased stack pointer is also missing.
