Unnecessary extra semicolons introduced for functions

```luau
local value = nil

(Foo :: any):Call()

local tbl = {}

(Foo :: any):Call()
```

... will add semicolons unnecessarily, leading to ...

```lua
local value = nil;

(Foo :: any):Call()

local tbl = {};

(Foo :: any):Call()
```

We don't need to add semicolons here, as they are not ambiguous statements. We would only need a semicolon if `nil` and `{}` were instead an identifier.
