Add a parameter to getCopyToParts and getCopyFromParts to specify whether
endian swapping should be done, and update the code to use it. This fixes
some register ordering issues on big-endian systems, such as PowerPC,
introduced by the recent illegal by-val arguments changes.

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

Replace ExpandScalarFormalArgs and ExpandScalarCallArgs with the newly
