Extern precompiled Mir GLAS requires additional API changes. The reduced example: ```d struct S(T) { size_t len; T ptr; } auto foo(S!(const(double)*) sl) { } S!(double*) a; const S!(double*) b; foo(a); // fails foo(b); // fails ```

Fixing this issue will allow also significantly reduce template bloat for generic code.
