`__emit(load.u.pri)` with pre/post operators

[Y-Less]

Issue description:

Calling a macro that includes load.u.pri with a parameter that has ++ or -- on totally elides the operator.

Minimal complete verifiable example (MCVE):

#define EXAMPLE(%0) __emit(load.u.pri %0)

main()
{
    new c;
    EXAMPLE(c++);
    printf("%d", c); // Should be 1, is 0.
}
