Compilation fails with assertion in constfold.c:608 or constfold.c:614 for the
following code:

bool foo(T)(T t)
{
    t >>>= 1;       // triggers assertion for ubytes and ushorts
    // t = t >>> 1; // this compiles with no errors
    return true;
}

void main()
{
    auto g1 = foo!ubyte(1); // Ok for runtime
    auto g2 = foo!ushort(1); // Ok for runtime

    // CTFE:
    enum e1 = foo!ubyte(1);  // Assertion failure: '0' on line 608 in file
'constfold.c'
    enum e2 = foo!ushort(1); // Assertion failure: '0' on line 614 in file
'constfold.c'
}
