vm: derive duplicated constants from Lisp origin.
Some constnats in vm.c are hand-duplicates of ones in
vm-param.tl. Let's put them in vmop.h instead, where they can
be generated by the genvmop.txr script.
The two new constants are anticipated for some upcoming
VM work.
* genvmop.txr: Generate the existing VM_LEV_BITS,
VM_LEV_MASK, VM_SM_LEV_BITS and VM_SM_LEV_MASK from the
Lisp constants. Also, let's add two new ones.
* vm.c (VM_LEV_BITS, VM_LEV_MASK, VM_SM_LEV_BITS,
VM_SM_LEV_MASK): Preprocessor symbols removed.
* vmop.h (VM_LEV_BITS, VM_LEV_MASK, VM_SM_LEV_BITS,
VM_SM_LEV_MASK): Preprocessor symbols generated here with
identical values.
(VM_MAX_LEV, VM_MAX_V_LEV): New constants.
