Optimization: Any globals only accessed in main should be turned in to locals #5

Closed HoneyPony closed 1 week ago

This would allow for any optimizations to locals, such as type-flow analysis / fence-elision / whatever, to be automatically applied to any variables that are only accessed in main, without any otherwise special logic.

Hmm, this is partially implemented by f7d9e8b, but apparently now globals are not being used at ALL by main(), which is incorrect.
