The exception handling intrinsics return values,
so must be lowered to a value, not nothing at all.
Subtle point: I made eh_selector return 0 and
eh_typeid_for return 1.  This means that only
cleanups (destructors) will be run as the exception
unwinds [if eh_typeid_for returned 0 then it would
be as if the first catch always matched, and the
corresponding handler would be run], which is
probably want you want in the CBE.

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

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.

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.

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.

New test case. DAGCombiner should be able to fold -sin(-x)
in -enable-unsafe-fp-math mode.
