e82a2d7373 Fix stores to global addresses 
Fix calls with no arguments

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.

552f6f5f4e Add support for adding 0.0 and -0.0 to the constant pool, since we lie and 
say that we support them, for the purposes of generating fsel instructions.

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 
LowerCallTo.
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.

ec87399dac Fix external symbol printing in the AsmPrinter. Tell the ISel that we 
don't support things like memcpy directly.  This allows a handful of the
Shootout programs to work, yay!

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.

bc14e623e3 Compare dependence analysis with llvm instructions versus machine instrutions. the problem with using machine instructions and alias analysis is that aa does not handle tmp instructions.

02a4d3bd9b Fix a bug that andrew noticed where we do not correctly sign/zero extend 
returned integer values all of the way to 64-bits (we only did it to 32-bits
leaving the top bits undefined).  This causes problems for targets like alpha
whose ABI's define the top bits too.

5ceaf630ab Fix a major problem with global variable initializers. This could cause 
us to have stuff pointing to the null pointer, which makes no sense
(the null ptr is an ssa value, not the null object)
