Bill Schmidt 013cbf2f1a [PowerPC] Support select-cc for VSX 
The tests test/CodeGen/Generic/select-cc.ll and
test/CodeGen/PowerPC/select-cc.ll both fail with VSX enabled.  The
problem is that the lowering logic for the SELECT and SELECT_CC
operations doesn't currently support the VSX registers.  This patch
fixes that.

In lib/Target/PowerPC/PPCInstrInfo.td, we have pseudos to handle this
for other register classes.  Similar pseudos are added in
PPCInstrVSX.td (they must be there, because the "vsrc" register class
definition appears there) for the VSRC register class.  The
SELECT_VSRC pseudo is then used in pattern matching for SELECT_CC.

The rest of the patch just adds logic for SELECT_VSRC wherever similar
logic appears for SELECT_VRRC.

There are no new test cases because the existing tests above test
this, along with a variant in test/CodeGen/PowerPC/vsx.ll.

After discussion with Hal, a future patch will add similar _VSFRC
variants to override f64 type handling (currently using F8RC).
