LegalizeTypes.  Correct the load logic so
that it actually works, and also teach it
to handle floating point extending loads.

llvm-gcc is now lowering va_copy on x86-64, so this completes
the fix for PR2230.

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.

Be more careful with insert_subreg and extract_subreg where either source or destination operand has already been coalesced with another register that's defined by a insert_subreg or extract_subreg.

Correlate stubs with functions in JIT: when emitting a stub, the JIT tells the memory manager which function
the stub will resolve.

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.

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.

VisualStudio project files updated.  #include <algorithm> added to make VisualStudio happy.  Also had to undefine setjmp because of #include <csetjmp> turning setjmp into _setjmp in VisualStudio.
