1d78cd0f03 Axe the constexpr expression evaluator
This avoids redundancy between them (and also having to port fixes and features)
The error messages have been preserved through a string reporting mechanism

cc59730c5b Cleanup the RPN evaluator somewhat
Make the bool field an actual bool
Rename `iReloc` to a more exact `isKnown` (as was already pointed out by some
comments)
Make the value of `BANK(symbol)` consistent when the argument is invalid

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.

This was made separate with the intention of supporting multiple versions,
but after some discussion this was decided against, so better improve

f2be601a13 Check "left" boundary as well in isLocationSuitable
"fixed" and "aligned" location checking advanced the target location to places
regardless of the associated free space, potentially breaking the assumption
that the location was always further in memory than the free space's base.

Rather than adding more code to try keeping that assumption true, harden
`isLocationSuitable` and handle that case as well.

ed72baca2a Make more symbol functions const
Can't hurt to specify those as they are now. Perhaps it'll enable slightly more
compiler optimizations, too?

93ee417567 Fix timestamp symbols on Windows (partially)
Windows does not honor `%F` nor `%T` in `strftime`. These are worked around
by writing the full format they serve as a short for.
However, Windows also treats `%z` and `%Z` identically, where SUS instead
requires `%z` to output a ±XXXX offset.
Since the current information is broken (no information), this isn't *breaking*
anything, but at least provides something a human will probably understand.
`__ISO_8601_UTC__` is unaffected because it hardcodes the timezone character,
only `__ISO_8601_LOCAL__` suffers from this.

a9cb4f8245 Make RGBASM overwrite output files atomically
Fixes rednex/#446.
I am not sure this is the best (in cases where the target directory
is not writable but the target file is), but maybe this can be
toggled via a flag, for example.

ISSOtm
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.

1fb9f90f0f Add -MT option
Allows overriding the output file in dependencies, which also allows
outputting those without also outputting the object file.
This, again, mimicks GCC's option.
