[committed] amdgcn: 64-bit vector shifts

[Andrew Stubbs]

I've committed this patch to implement V64DImode vector-vector and 
vector-scalar shifts.

In particular, these are used by the SIMD "inbranch" clones that I'm 
working on right now, but it's an omission that ought to have been fixed 
anyway.

Andrewamdgcn: 64-bit vector shifts

Enable 64-bit vector-vector and vector-scalar shifts.

gcc/ChangeLog:

        * config/gcn/gcn-valu.md (V_INT_noHI): New iterator.
        (<expander><mode>3<exec>): Use V_INT_noHI.
        (v<expander><mode>3<exec>): Likewise.
