i965/fs: Add support for specifying register horizontal strides

Graphics / Mesa 3D Graphics Library / Mesa - Francisco Jerez [riseup.net] - 12 February 2014 16:07 UTC

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.
