965e6efe24 Add a basic test-case for passing and returning <4 x double> and 
<8 x float> values on X86.

eb46e6e629 Vector results may be returned in XMM0 and XMM1, not just XMM0. With 
the recent lowering changes, this allows types like <4 x double> to
be returned, using two vector registers.

68f0cbccfb Replace ExpandScalarFormalArgs and ExpandScalarCallArgs with the newly 
refactored getCopyFromParts and getCopyToParts, which are more general.
This effectively adds support for lowering illegal by-val vector call
arguments.

5fe8266d04 Teach GetNegatedExpression to negate 0-B to B in UnsafeFPMath mode, and 
visitFSUB to fold 0-B to -B in UnsafeFPMath mode. Also change visitFNEG
to use isNegatibleForFree/GetNegatedExpression instead of doing a subset
of the same thing manually.

This fixes test/CodeGen/X86/negative-sin.ll.

f46ec01deb New test case. DAGCombiner should be able to fold -sin(-x)
