The compilation cache doesn't know about REPL mode. This means that
non-REPL mode compiled scripts are successfully found for their
REPL mode equivalent and vice versa.

This CL disables the compilation cache for REPL mode scripts.
Performance is not really a concern as DevTools console inputs
are usually very small.
