Subject: i965/fs: Remove the param_index/param_offset indirection.
X-Git-Tag: android-x86-4.4-r1~2170
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=f189570ccf60ab665cbe9feeff52685600f8163d;p=android-x86%2Fexternal-mesa.git

i965/fs: Remove the param_index/param_offset indirection.

Now that ParameterValues doesn't change across the visitor, we don't
need to go through this.
