1303e72c66 refactor handling of symbolic constant folding, picking up
a few new cases( see Integer/a1.ll), but not anything that
would happen in practice.

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.

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.
