`x: Type` parameter is mistaken as anytype parameter

Zig Version

0.11.0-dev.4404+4f6013bf5

Steps to Reproduce and Observed Behavior

Probably a duplicate but

test {
    writeIntLittle(u64, @bitCast(packed struct { hi: u32, lo: u32 }{ .hi = 0, .lo = 0 }));
}

fn writeIntLittle(comptime Type: type, x: Type) void {
    _ = x;
}

$ zig test x.zig
x.zig:2:25: error: @bitCast must have a known result type
    writeIntLittle(u64, @bitCast(packed struct { hi: u32, lo: u32 }{ .hi = 0, .lo = 0 }));
                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
x.zig:2:25: note: result type is unknown due to anytype parameter
x.zig:2:25: note: use @as to provide explicit result type

Expected Behavior

Test passes.
