iris: Fix ALT mode regressions from shader cache
We were checking this based on nir->info.name, but with the shader cache enabled, nir_strip throws out the name, causing us to use IEEE mode for ARB programs. gl-1.0-spot-light regressed because it wants ALT mode for 0^0 behavior. Fixes: dc5dc727d59 iris: Serialize the NIR to a blob we can use for shader cache purposes.
