Decay deduced function return types

[sdkrystian]

Even though parameters should have their type preserved to reflect how they were written, deduced return types should be automatically decayed because the type is not explicitly written. For example:

struct A
{
    char data[20];

    auto f() { return data; }
}

Currently (with recursive TypeInfo) the return type of f is extracted as char[20]. The actual return type of the function is char*.
