Immutable arrays for the recursive case as well
Revert "Fix bug #67064 in a BC safe way"

This reverts commit 1a4a9eede59b853f11e8e8b965e5f715f53da8f7.

Conflicts:

Weaker recursion during pre-evaluation
Rename _tmp_compile_const_expr

Also remove recursive immutization of arrays there, because this
is already handled when the array is created.
Use ZVAL_COPY until proven wrong
Disable restrictions regarding arrays in constants at run-time.
