Optimize displacements, don't pessimize them. When running in the
optimizer, we always keep track of when a reference is forward. That

Only be optimistic about the reachability of a symbol with NO_SEG if

then it is an absolute symbol and need to be treated as such.

br704736: handle deep context-local macros
The documentation says that constructs with %$...$foo can be used
to access macros from deeper in the context stack. From what
I can tell, that has never actually worked, since we'd enter names
like %$foo into the context-local macro name table. Instead, only
insert the tail of the macro name into the context-local table;
expand get_ctx to also return a pointer to the macro name proper;
this is rather straightforward since we'd usually save away that
name at the point get_ctx is called anyway.
