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.

5b98beec8b Use left recursion instead of right

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!

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

598c923506 Use callback for PC's value
This causes it to auto-update whenever the current section's attributes are
updated, simplifying the code and eliminating redundancy.
This should also overall reduce overhead (one extra function call on each
PC evaluation, but less bookkeeping for each byte output)

af6f62701c Remove ambiguous charmap syntax
The syntax was `charmap "anything", "string"`; the second string was
already handled by `const`, but to the same effect... the ambiguous
declaration has been removed, leaving us at "only" two reduce/reduce
conflicts.

12f2f654dd Add -MG
This option allows for automatic dependency detection and generation:
as soon as a missing file is found, it is output to the dep file, and
assembly immediately aborts. (No .o file is produced, even if `-o` was
speicified.) This doesn't cause an error, either; the point is that once
the file is added to the dep file, the Makefile is re-parsed, and this
time the file will be generated, so the dep list builds up automatically.
This mimicks GCC's option and behavior.

Stop using that bitfield for everything, including what can be determined otherwise
It also makes it easier to have a sane state, since some bits were (supposedly)
mutually exclusive
