Kenneth Graunke 9dd6fcd9ec intel/compiler: UNDEF SubgroupInvocation's register 
This value takes a few instructions to create, involving expanding
V-immediates, adding 8 for SIMD16, and so on.  We can mark it UNDEF
so that it's clear that although these are partial writes, we are
actually defining the entire value.
