Fix fuzzer-discovered optimizer crash. The CFG/definition map are no longer valid after replacing an expression entirely. Swizzle-of-swizzle optimization was another case where the optimizer would replace an expression wholesale, but failed to set the needs-rescan flag.

Fix various fuzzer-generated tests. Two of the tests are now (correctly) detected as invalid code, but were previously checked into /shared/ because they compiled when the fuzzer first reported them (that is, after the crash was fixed). These have been moved into the /errors/ test folder. One of the tests was only generating an error because its main function was named `a` instead of `main`, so I renamed it to `main`.
