Dale Johannesen a2b3c175db Fix for PR 1505 (and 1489). Rewrite X87 register 
model to include f32 variants.  Some factoring
improvments forthcoming.

Dan Gohman 9ff9908413 Add a basic test-case for passing and returning <4 x double> and 
<8 x float> values on X86.

Dan Gohman f9ae1c6001 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.

Dan Gohman 533dd16a7f 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.

Dan Gohman 9a70823375 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.
