* Make tyConSingleDataCon_maybe more forgiving
Ignore-this: f60ab4d3e79b2c18499d0bfcf1949c85
This function was barfing on a type family tycon; which in turn
crashed the compiler (when -ticky is in use) because of the use in
CmmTicky.hs. There's no need for it to reject such tycons, so I just
made it return Nothing rather than falling over.
M ./compiler/types/TyCon.lhs -7 +4
