2a00530fa7 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.

destructor. Just add the do-nothing virtual destructor.

27134f31f2 Older compilers won't like the inline virtual destructor in the header file 
so we put the destructor in Pass.cpp and make it non-inline.

f6e98c8cf5 Change some old-style casts to C++ style casts to avoid warnings in XPS 
compilation. This change has been waiting in the wings for a long time but
since Misha just did a global change, I figured now was the time to commit
it.

a416f4bbf3 * store immediate values as int64_t, not int. come on, we should be happy 
when there are immediates, let's not worry about the memory overhead of
this :)

* add addU64Imm(uint64_t val) to machineinstrbuilder

(seriously: this seems required to support 64-bit immediates cleanly. if it
_really_ gets on your nerves, feel free to pull it out ;) )

coming up next week: "all your floating point constants are belong to us"

3a10f491f0 add support for prefix/suffix strings to go around GlobalValue(s) 
(which may or be function pointers) in the asmprinter. For the moment,
this changes nothing, except the IA64 backend which can use this to write:

  data8.ua  @fptr(blah__blah__mangled_function_name)

  (by setting FunctionAddrPrefix/Suffix to "@fptr(" / ")")
