test: only require issue11674 errors with gc compiler

Browse Source 
The gofrontend code sees that the denominator is not zero,
so it computes the values. Dividing zero by a non-zero value
produces zero. The language spec doesn't require any of these
cases to report an error, so make the errors compiler-specific.
