It'd be useful to add tests to see if the relevant ternlog patterns get correctly canonicalized to the useful patterns listed here: http://www.0x80.pl/articles/avx512-ternary-functions.html

In particular - ensuring we fold ternlog -> bitselect -> regular select (if driven by a compare / sign-extended bool vector), and maybe the one-bit-set pattern are of particular interest?
