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.

9d224ae29b Support indexed loads and stores. This drops Shootout/matrix time from
18.8 to 14.8 seconds.  The Pattern ISel is now often faster than the
Simple ISel, esp. on memory intensive code.

47fed18416 Assorted fixes:
* Stop being pessimistic about output register allocation
  * Start to handle function descriptors: compute target GPs and so on
  when doing indirect calls etc. Not there yet, though. For the moment,
  we try to use _indirect_ branches wherever possible, to stress test
  function descriptors.
  * FP divide-by-zero should work now
  * add varargs (it doesn't work, though)

At this point, all of SingleSource passes (modulo C++ tests that are due
to issues with the CFE, see note in the README.) Much of MultiSource also
passes although there's still a ton of bugs around. Something for me to
work on tomorrow, then. :)

11ff0a2a5f add what we need to fudge a 'floating point conditional move', this is
used to get FP div-by-zero working properly (shunt the right answer
depending on how frcpa sets its predicate output)

17ff2b3a87 Pass the correct values to the chain argument for node construction during

Handle ISD::ADD in SelectAddr, allowing us to have nonzero immediates for
loads and stores, amazing!

de4aac1374 Rewrite LowerCallTo and Select(ISD::CALL) to properly handle float varargs
Tell the SelectionDAG ISel to expand SEXTLOAD of i1 and i8, rather than
  complicate the code in ISD::SEXTLOAD to do it by hand
Combine the FP and Int ISD::LOAD codegen
Generate better code for constant pool loads

As a result, all of Shootout, and likely many other programs are now
working.

abb59a3c21 Instead of setting up the CFG edges at selectiondag construction time, set
them up after the code has been emitted.  This allows targets to select one
mbb as multiple mbb's as needed.
