bd19c1d25f Try several things. 1) drop /i from FP ops 2) factor out FP to Int moves and provide 21264 support for those 3) match not 4) match ornot andnot xornot

23ef46ddca Change the ActualCallees callgraph from hash_multimap<Instruction,Function> 
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.

63f75bdf49 ia64 asmprinter fixes: 
- 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.

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(" / ")")

8644181cd6 Several changes mixed up here. First when legalizing a DAG with pcmarker, 
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.
