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.

Summary:
The linear parameter token in the mangling function must be multiplied
by the pointee size in bytes when the parameter is a pointer.

Patch fixes the problem with the functions marked as `declare simd`. If
the canonical declaration does not have associated `declare simd`
construct, we may not generate required code even if other
redeclarations are marked as `declare simd`.

only.
Added support for -fopenmp-simd option that allows compilation of
simd-based constructs without emission of OpenMP runtime calls.

Previously the attributes were emitted only for function definitions.
Patch adds emission of the attributes for function declarations.
