i965: Use a UW source type for CS_OPCODE_CS_TERMINATE.

SIMD16 compute shaders use a send(16) with mlen 1 for the EOT message,
using a source of g127 for the single register.  With a UD type, this
supposedly could read g128, which doesn't exist, causing the simulator
to get cranky.  Use a UW type to avoid this.
