a0b34d6c4a Sparc: Mark functions calling llvm.vastart and llvm.returnaddress intrinsics as non-leaf functions.

ddb14ce76c Passing arguments to varags functions under the SPARC v9 ABI. 
Arguments after the fixed arguments never use the floating point
registers.

da8768b2dd Compile varargs functions for SPARCv9. 
With a little help from the frontend, it looks like the standard va_*
intrinsics can do the job.

Also clean up an old bitcast hack in LowerVAARG that dealt with
unaligned double loads. Load SDNodes can specify an alignment now.

Still missing: Calling varargs functions with float arguments.
