[REG2.065a] Issue 11755 - Operator <>= and !<>= with arrays make internal error in e2ir

https://d.puremagic.com/issues/show_bug.cgi?id=11755

It's a git-head regression caused by #2960.

Currently backend layer implicitly translates NCEG operators to the corresponding integer operators in non-floating comparisons. If no corresponding operator exists, it had been reported backend error, and now ICE causes.
