Crash with structures containing generic pointers

[bmanga]

The following code:

typedef struct { float *data; } Data;

kernel void k(global float *data_out_raw) {
    Data d {data_out_raw};
}

When compiled with -cl-std=CLC++ -inline-entry-points results in

Assertion failed: (castIsValid(op, S, Ty) && "Invalid cast!"), function Create, file Instructions.cpp, line 3682.
