There is some strange interaction between -mmsa and -mloongson-mmi causing
this. It can be reproduced by building pixman (which enables -mloongson-mmi by
default) with -mmsa.

It's not just comparisons. <<, >>, /, * also don't work. AFAICT only bitwise
operations and +/- work, as well as everything with a 64-bit element type
(i.e., a vector of one element)… 8/16/32-bit elements
