to std::set<std::pair<Inst,Func>> to avoid duplicate entries.

This speeds up the CompleteBU pass from 1.99s to .15s on povray and the
eqgraph passes from 1.5s to .16s on the same.

  - turn off assembler's autoalignment
  - set FunctionAddrPrefix/Suffix so that .data8 entries pointing to
    functions have their value wrapped in @fptr(), so that a function
    descriptor will be materialized for that function.

(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(" / ")")

dont' regen the whole dag if unneccesary.  Second, fix and ugly bug with
the _PARTS nodes that caused legalize to produce multiples of them.
Finally, implement initial support for FABS and FNEG.  Currently FNEG is
the only one to be trusted though.

Teach the SelectionDAG code how to expand and promote it
Have PPC32 LowerCallTo generate ISD::UNDEF for int arg regs used up by fp
  arguments, but not shadowing their value.  This allows us to do the right
  thing with both fixed and vararg floating point arguments.
