[nvptx] Use atom.and.b64 instead of atom.b64.and

Browse Source 
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.
