does not work because of 0; 2>0 but -2U is also >0.

26b54dda58 Implement a bit more softfloat support in 
LegalizeTypes.  Correct the load logic so
that it actually works, and also teach it
to handle floating point extending loads.

98ca33cb59 Fix the handling of va_copy on x86-64. As of llvm-gcc r49920 
llvm-gcc is now lowering va_copy on x86-64, so this completes
the fix for PR2230.

88d2a8459b Provide an explicit list of operands to MakeLibcall, 
rather than having it suck them out of a node.  Add
a bunch of new libcalls, and remove dead softfloat
code (dead, because FloatToInt is used not Expand
in this case).  Note that indexed stores probably
aren't handled properly, likewise for loads.

55efcf86e9 Run SimplifyLibCalls near the beginning, not at 
the end.  It is now run at the same moment as in
llvm-gcc.  Also, run StripDeadPrototypes at the
end, just before running DeadTypeElimination.
This may be useful when doing LTO.  Note that
llvm-gcc runs StripDeadPrototypes but not
DeadTypeElimination.

728d59166f Ongoing work on improving the instruction selection infrastructure: 
Rename SDOperandImpl back to SDOperand.
Introduce the SDUse class that represents a use of the SDNode referred by
an SDOperand. Now it is more similar to Use/Value classes.

Patch is approved by Dan Gohman.

6d05ce493b Rewrite LiveVariable liveness computation. The new implementation is much simplified. It eliminated the nasty recursive routines and removed the partial def / use bookkeeping. There is also potential for performance improvement by replacing the conservative handling of partial physical register definitions. The code is currently disabled until live interval analysis is taught of the name scheme. 
This patch also fixed a couple of nasty corner cases.

64fc7a4268 XFAIL this test for the moment. The real solution is to prevent ADCE 
from transforming loops and adding a separate loop pass for removing
loops with know trip counts.  Until that happens, ADCE is miscompiling this code.

cf79877623 Recreate the size SDNode instead of reusing the old one in the x86 
memcpy lowering code; this ensures that the size node has the desired
result type. This fixes a regression from r49572 with @llvm.memcpy.i64
on x86-32.
