nv50/ir: fix cutoff for using r63 vs r127 when replacing zero
The only effect here is a space savings - 822 programs in shader-db affected with the following overall change: total bytes used in shared programs : 44154976 -> 44139880 (-0.03%) Fixes: 641eda0c (nv50/ir: r63 is only 0 if we are using less than 63 registers) Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Cc: "11.0 11.1" <mesa-stable@lists.freedesktop.org> (cherry picked from commit f920f8eb026d39c0adb547a90399e76b8351fec6)
