2. The very case the comment describes actually makes the load

My previous commit had an incomplete message, it should have been:

make the 'fp return in ST(0)' optimization smart enough to
look through token factor nodes.  THis allows us to compile
testcases like CodeGen/X86/fp-stack-retcopy.ll into:

_carg:
subl $12, %esp
call L_foo$stub
fstpl (%esp)
fldl (%esp)
addl $12, %esp
ret

instead of:

_carg:
subl $28, %esp
call L_foo$stub
fstpl 16(%esp)
movsd 16(%esp), %xmm0
movsd %xmm0, 8(%esp)
fldl 8(%esp)
addl $28, %esp
ret

Still not optimal, but much better and this is a trivial patch.  Fixing
the rest requires invasive surgery that is is not llvm 2.2 material.
