[Mesa-dev] [PATCH] tgsi_exec: Fix mask calculation for emit_kill_if.

[jfonseca at vmware.com]

From: José Fonseca <jfonseca at vmware.com>

Same as Si Chen's commit e7a5905d8a3960b0981750f8131e3af9acbfcdb8 for
tgsi_exec module.

Not actually tested, because softpipe is failing the test that caught
this bug due to unrelated issues.
