Tracking Issue for `global_asm!` in statement positions

The feature gate for the issue is #![feature(global_asm_statement_position)].

About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.
Discussion comments will get marked as off-topic or deleted.
Repeated discussions on the tracking issue may lead to the tracking issue getting locked.

Description

Currently global_asm! is only allowed in a module root. This feature allows it to appear in any position an item can appear.

mod foo {
    // This was previously the only allowed position.
    global_asm!("");

    fn bar() {
        // Like any item, `Baz` can be added inside a function,
        // but has no relation to the parent function `bar()`.
        struct Baz;

        // This is not allowed today, its what this feature enables.
        global_asm!("");
    }
}
