This seems to be surreptitiously adding another mechanism to check for the
presence of a vector math routine. Under what circumstance do you need to check
for the cost of something that might not exist? I would expect TLI to be
queried directly as part of a transformation and once they've concluded a
vector math call exists then they'd simply query the cost of the call.
