/* A store instruction can always corrupt part of the fakestack,
* so some items of the stack have to be removed (i.e. pushed on
* the real stack or stored in a register). Registers on the
* fakestack will never be corrupted, because they can never be
* the destination.
* For most store instructions (e.g. sil,stf) we have hardly any
* idea what the destination will be, so everything on the
* fakestack (except registers) is removed (i.e. remove(MEM_ALL)).
* For a stl,sdl,ste and sde we remove only those items that may
* be affected, assuming that a stl only affects locals and a
* ste only affects externals. Care has to be taken that doubles
* and singles may overlap, e.g. "lol 6 sdl 4".
* Furthermore, stacktoken instances that resulted from a lof,lif
* or loi may be corrupted too.

/* In general, array references are resolved via a subroutine call.
* Only for two very simple cases we use a more efficient method.
* The array must be static, i.e. its element size and its index
* range must be static. In these cases the array descriptor will
* normally be stored in a rom and an element will be accessed via
* the sequence "lae lar", in which lae puts the address of the
* descriptor on the stack. The efficient method is used only if the
* element size is 2 or 4 bytes. We also make sure that
* the offset generated fits in 8 bits.
