i965/fs: Add support for specifying register horizontal strides.
v2: Some improvements for copy propagation with non-contiguous
register strides and mismatching types.
v3: Add example of the situation that the copy propagation changes are
intended to avoid. Clarify that 'fs_reg::apply_stride()' is expected
to work with zero strides too.
