* Fix functions that take more than 32 bytes of args
* Alignment of doubles in structs is 4 bytes, not 8
* Fix passing long args: rN = hi, rN+1 = lo
* Rewrite signed divide
* Rewrite Intrinsic::returnaddress

better here, but this will do for now.  This implements
instcombine/cast.ll:test17/18 as well.

`-> asm printer updated to not print out those registers with the call instr

All of Shootout tests now work.  Great thanks to Nate Begeman for the patch!

* Fn args passed in registers are now recorded as used by the call instruction
`-> asm printer updated to not print out those registers with the call instr
* Stack frame layout in prolog/epilog fixed, spills and vararg fns now work
* float/double to signed int codegen now correct
* various single precision float codegen bugs fixed
* const integer multiply codegen fixed
* select and setcc blocks inserted into the correct place in machine CFG
* load of integer constant code optimized

is a simple change, but seems to improve code a little.  For example, on

* vreg <-> vreg joining now works, enable it unconditionally when joining
  is enabled (which is the default).
* Fix a serious pessimization of spill code where we were saying that a
  spilled DEF operand was live into the subsequent instruction.  This allows
  for substantially better code when spilling starts to happen.
