This string mixin generator allows one to create tagged pointers inside structs and classes.
A tagged pointer uses the bits known to be zero in a normal pointer or class reference to store extra information.
For example, a pointer to an integer must be 4-byte aligned, so there are 2 bits that are always known to be zero.
One can store a 2-bit integer there.
The example above creates a tagged pointer in the struct A. The pointer is of type
uint* as specified by the first argument, and is named x, as specified by the second
argument.
Following arguments works the same way as bitfield's. The bitfield must fit into the
bits known to be zero because of the pointer alignment.
