Honestly, I don't know what I was thinking - we are emitting a single
spill/fill message here, but were counting it as 2 spill/fills in SIMD32
shaders. So our eventual shader stat reporting would subtract the
number of spills and fills from send_count, and get a negative number,
wrapping around to just shy of UINT32_MAX. That's way too many sends.
This is especially noticable on Xe2 which often uses SIMD32 shaders.
