Lots of tests fail with --conditionalizePermissions

[marcoeilers]

At least the following:

• issues/carbon/0179 (unsound because of incorrect treatment of perm-expressions, will be fixed in PR Not pushing conditions using permission introspection further in #853)
• issues/silicon/0008 (expected incompleteness, --conditionalizePermissions introduces disjunctive aliasing, works with MCE)
• issues/silicon/0114 (default Silicon is incomplete, test fails because --conditionalizePermissions leads to correct output)
• issues/silicon/0282 (expected incompleteness, --conditionalizePermissions seems to trigger a general Silicon triggering issue)
• issues/silicon/0324 (expected incompleteness, --conditionalizePermissions introduces a situation where greedy Silicon is incomplete, works with MCE)
• issues/silicon/unofficial003 (used to trigger a bug in Silicon, fixed in PR Recording constraints for newly-introduced variables during state consolidation #852)
