Would you review the following change?
This change adds support for vectorized arithmetic calculation with SLP.
The to_vr function is added to convert VSR to VR. Currently, vecX is
associated with a VSR class vs_reg that only defines VSR32-51 in ppc.ad,
which are exactly overlapped with VRs. Instruction APIs receiving VRs use
the to_vr via vecX. Another thing is the change in sqrtF_reg to enable the
matching with SqrtVF. I think the change in sqrtF_reg would be fine due to
the ConvD2FNode::Value in convertnode.cpp.
I confirmed this change with JTREG. In addition, I used attached micro
