I created a fp16 variant:
https://git.libre-soc.org/?p=ieee754fpu.git;a=blob;f=fp16mul_test.smt2;h=6ad9dc798eb34c72357c3d94d953de01493a5795;hb=c17c88ffba83c546ae439238fdd43adce3992f53

currently running z3 and cvc5, though cvc5's support for stuff other than
f32/f64 is experimental and may be broken.
