[nvptx] Use atom.and.b64 instead of atom.b64.and
The ptx manual prescribes the instruction format atom{.space}.op.type but the
compiler currently emits:
...
atom.b64.and %r31, [%r30], %r32;
...
which uses the instruction format atom{.space}.type.op.
Fix this by emitting instead:
...
atom.and.b64 %r31, [%r30], %r32;
...
Tested on nvptx.
gcc/ChangeLog:

* config/nvptx/nvptx.md (define_insn "atomic_fetch_<logic><mode>"):
Emit atom.and.b64 instead of atom.b64.and.
