game instance tree state lost when indexing up ancestors using .Parent

[matthargett]

when trying to require anything from script.Parent, I get messages like this:

src/Array/concat.lua(3,25): TypeError: Key 'isArray' not found in class 'Instance'

it looks like in the globalTypes.d.lua, it declares script: LuaSourceContainer. I can change that to any and it no longer emits this error as a workaround. It would be nice to not have to trade one for the other, though.

note that it doesn't actually affect require, but just indexing the tree.

require(script.Parent.Child) will resolve correctly and return typed code but the script.Parent.Child indexing part will currently error as we lose the game tree state and don't know that Child is a descendant of script.Parent.

80f68a9 temporarily marks script as any, which will hopefully silence most of these spurious type errors for now
