When optimizations are enabled, primitive string literals can be
inlined, which can create two copies of a string constant with different
addresses. We want to avoid this behavior at all costs in the `GEq1`
test, since the output depends on the result of `eqAddr#`. We prevent
such inlining through use of the `{-# NOINLINE #-}` pragma.

Fixes #11292.
