broken llvm module when inlining an `await` expression

zig commit: 236db62

fn alert(msg_ptr: [*]const u8, msg_len: usize) void {}

fn asyncFn(a: usize) callconv(.Async) usize {
    return a;
}

fn amain() void {
    const str = "hello";
    var v = async asyncFn(1);
    var zero: usize = 0;
    alert(str[zero..].ptr, await v);
}

pub fn main() void {
    _ = async amain();
}

this seems to be caused by the fact that the first parameter of alert is of type [*]const u8. changing the type or removing the first parameter seems to fix the compilation error. assigning the value of the await expression to a temporary variable also fixes the problem.

fn alert(msg_ptr: [*]const u8, msg_len: usize) void {}

fn asyncFn(a: usize) callconv(.Async) usize {
    return a;
}

fn amain() void {
    const str = "hello";
    var v = async asyncFn(1);
    var zero: usize = 0;
    var tmp = await v;
    alert(str[zero..].ptr, tmp);
}

pub fn main() void {
    _ = async amain();
}
