Compile some standalone tests to bytecode

* test-suite/standalone/test-out-of-memory:
* test-suite/standalone/test-stack-overflow: Compile these files before
  running them.  That way, recursion can check the stack-overflow
  mechanism instead of the memory allocation mechanism.  We compile
  beforehand as a prepass so as not to impose an rlimit on a Guile that
  previously ran auto-compilation.
