Allow empty catch type to catch all exceptions

[thekid]

Form without variable

Will catch but not assign any variable:

try {
  …
} catch (IllegalArgumentException) {
  // Handle exception
}

Form without type

Will catch all exceptions - a shorthand for catch (\Throwable $e):

try {
  …
} catch ($e) {
  // Handle exception
}

Anonymous catch

Will catch all exceptions and not assign any variable:

try {
  …
} catch {
  // Handle
}
