2f16e82cf7 Improve PC offset management 
Basically make it always point to the instruction's first byte.
This was the behavior all whom I asked to intuitively expected.

2f466c2939 Revamp macro arg system 
This should significantly improve performance: on pokecrystal builds, perf
reported as much CPU time spent on `yyparse` as on `sym_UseNewMacroArgs`
Measurements show ~6 seconds of improvement on that codebase.

This also fixes #321, as a bonus, due to saner management!

ffdb1fbfe5 Split macro arg management into its own file 
It has no relation to symbols, and helps a tiny bit deflate `symbol.c`

7c8eba9fd2 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.

4cc24f4369 Add ds cnt, byte syntax 
As suggested by https://github.com/rednex/rgbds/issues/350#issuecomment-498030458
The order `count` then `byte` was decided after some discussion:
- First argument consistent with single-arg syntax
- Intuitive at least to some people other than myself
- Consistent with other assemblers, at least ca65
