Jennifer Yu a6cdac48ff Eliminate extra set of simd variant function attribute. ...

Current clang generates extra set of simd variant function attribute
with extra 'v' encoding.
For example:
_ZGVbN2v__Z5add_1Pf vs _ZGVbN2vv__Z5add_1Pf
The problem is due to declaration of ParamAttrs following:
    llvm::SmallVector<ParamAttrTy, 8> ParamAttrs(ParamPositions.size());
where ParamPositions.size() is grown after following assignment:
    Pos = ParamPositions[PVD];
So the PVD is not find in ParamPositions.

The problem is ParamPositions need to set for each FD decl. To fix this

Move ParamPositions's init inside while loop for each FD.
