memlayout: Add symbols for stage bounds
Stages are inconsistent with other memlayout regions in that they don't
have _<name> and _e<name> symbols defined. We have _program and
_eprogram, but that always only refers to the current stage and
_eprogram marks the actual end of the executable's memory footprint, not
the end of the area allocated in memlayout. Both of these are sometimes
useful to know, so let's add another set of symbols that allow the stage
areas to be treated more similarly to other regions.
