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.

Cleaned up GRConstants::AddBinding to not directly reference the
predecessor node.  Now we just manipulate the current state, and a driver
function creates nodes as needed.

Move some calls to getVRegDef higher in the callgraph, so they don't get executed as frequently in performance sensitive code.

Finish up handling all permutations of "complex int" (in Sema::UsualArithmeticConversions()).
A FIXME remains to verify the conversion rules are consistent with GCC.

- Change Type::isComplexType() to exlude GCC's complex integer extension. In general, we will keep the lowest level Type predicates "pure" (i.e. true to the C99 spec). 
- Modify Sema::UsualArithmeticConversions() to work with the new definition of Type::isComplexType().

This is a nice cleanup and also fixes a bug submitted by Eli (which I've added to the test suite).
