Hal Finkel ba51ae6864 [PowerPC] Support non-direct-sub/superclass VSX copies 
Our register allocation has become better recently, it seems, and is now
starting to generate cross-block copies into inflated register classes. These
copies are not transformed into subregister insertions/extractions by the
PPCVSXCopy class, and so need to be handled directly by
PPCInstrInfo::copyPhysReg. The code to do this was *almost* there, but not
quite (it was unnecessarily restricting itself to only the direct
sub/super-register-class case (not copying between, for example, something in
VRRC and the lower-half of VSRC which are super-registers of F8RC).

Triggering this behavior manually is difficult; I'm including two
bugpoint-reduced test cases from the test suite.
