320181576e iniital checkin of ELFWriter header. 
For now, the elf writer is only capable of emitting an empty elf file, with
a section table and a section table string table.  This will be enhanced
in the future :)

* Use C++ style casts, not C style casts
* Abstract base classes should have virtual destructor.

26a35003bf Forgot to commit this earlier. Its part of the simplify-libcalls 
enhancement for ffs, ffsl, and ffsll optimizations. We can't do the opt
unless we also have the at least ffsll function. Notably SVR4 doesn't.

2d86ea21dd Implement Value* tracking for loads and stores in the selection DAG. This enables one to use alias analysis in the backends. 
(TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*.  Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null.
