778ad67a26 Make the unary operator case a bit faster, since casts are the only kind of unary operation.

model to include f32 variants.  Some factoring
improvments forthcoming.

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.

c6bdcfa8c0 Add new TargetLowering code to provide the final register type that an 
illegal value type will be transformed to, for code that needs the
register type after all transformations instead of just after the first
transformation.

Factor out the code that uses this information to do copy-from-regs and
copy-to-regs for various purposes into separate functions so that they
are done consistently.
