Because a local symbol is necessarily a label, the disambiguation
is not necessary. This is a first step towards fixing #457 .

Implement unionized sections in RGBASM
...
This touched a lot more code than initially expected, for two reasons.
First, this broke a big RGBASM assumption: that sections are always being
written to at their end. This plus other problems required touching
basically the entirety of `section.c`.
Second, I tried different solutions to solve the above problem, and along
the way I cleaned up many things around. (I believe that keeping this to
"cleanup" commits yields subpar results, and since it's boring they get
postponed anyways.)
RGBLINK support still needs to be added, but this will come next.

This should significantly improve performance: on pokecrystal builds, perf
reported as much CPU time spent on `yyparse` as on `sym_UseNewMacroArgs`

Remove error message causing segfault
...
This was utterly stupid. The check right above ensured that `sym` was NULL,
ergo that the argument to `yyerror` *would* segfault.
The only two call sites cannot pass a non-NULL pointer anyways, which I'm
betting is why this went unnoticed.
I did what an optimizing compiler would do anyways: remove the dead code.
