Summary:
While the symbolic heap analysis ends its search upon hitting the
bound on recursion depth, the used-globals analysis should instead
simply skip recursive calls beyond the depth. Note that this is
unsound for arbitrary abstract domains, however, and the flag
controlling this feature should be used with caution.
Note that procedure calls are still not handled correctly, since
Used_globals.exec_intrinsic does not properly check whether callees
are intrinsic. A forthcoming commit will fix that, as well.
