LDC crashing on compiling code in 32-bit mode

[naydef]

Add -m32 or --arch=x86

struct Vector
{
    float x, y, z;
}

struct QAngle
{
    float x, y, z;

    QAngle opOpAssign(string op)(const(QAngle))
    {
        return this;
    }
}

void OnUserCmdPre()
{
    Vector ss;
    QAngle dd;
    dd -= cast(QAngle)ss;
}

void main() {}

Error message

#0 0x0000000005303243 llvm::sys::PrintStackTrace(llvm::raw_ostream&, int) (/home/ndf/dlang/ldc-1.30.0-beta1/bin/ldc2+0x5303243)
/home/ndf/dlang/ldc-1.30.0-beta1/bin/ldc2 failed with exit code -11.

Tested with LDC 1.30.0 beta1 and with LDC-nightly and they both crash.

Thx for the report. - The issue is a general poor handling of type repaints, in this case an implicit QAngle to const(QAngle) repaint of the cast expression. We apparently don't expect structs to ever end up in DtoPaintType().
