intel/fs: Disable SIMD32 dispatch for fragment shaders with discard.

Current discard handling requires dedicating the second flag register to
discard.  However, control-flow in SIMD32 requires both flag registers
so it's incompatible with the current discard handling.  Just don't
support SIMD32+discard for now.
