Function declared with return type should emit error when nothing return

[MaxGraey]

EDITED

This examples successfully compile:

export function foo(): i32 { return; }

But expected:

error TS2355: A function whose declared type isn't 'void' must return a value.

It looks like some of these functions aren't actually compiled due to not being referenced / exported. This yields the proper diagnostics for example:

export function foo(): i32 {}

This is actually not emitting the expected diagnostic:

export function foo(): i32 { return; }

But this does:

export function foo(): void { return 1; }

For sure! So this is only relevant for the second case.
