2e1327b6b2 * use pooled constant references for the parameter locations as more often than not they're equal between multiple methdos (e.g. the Self argument is always the same)

in the i8086-msdos 'ports' unit, but will be enabled on other targets (e.g.
  go32v2) in the future as well. 32-bit 'in' and 'out' not inlined on i8086, but
  will be on i386 and x86_64.
