The unique address space, for allocating temporary registers,
is used for both registers needed by the pcode translation
engine and, later, by the simplification engine.  This routine
sets the boundary of the portion of the space allocated
for the pcode engine, and sets the base offset where registers
created by the simplification process can start being allocated.
@param val is the boundary offset
