ce6b27cfae [qfcc] Add failing test for array life
It seems that the optimizer keeps array assignments live when passing
the array as a pointer, but not when passing the address of an element.
Found when testing the following code:

    BasisBlade *pga_blades[16] = {
        blades[1],  blades[2],  blades[3],  blades[4],
        blades[7],  blades[6],  blades[5],  blades[0],
        blades[8],  blades[9],  blades[10], blades[15],
        blades[14], blades[13], blades[12], blades[11],
    };
    BasisGroup *pga_groups[4] = {
        [BasisGroup new:4 basis:&pga_blades[ 0]],
        [BasisGroup new:4 basis:&pga_blades[ 4]],
        [BasisGroup new:4 basis:&pga_blades[ 8]],
        [BasisGroup new:4 basis:&pga_blades[12]],
    };

Only the first element of pga_blades is being assigned in the optimized
code, but everything is correct when not optimizing.
