aa90a53f34 Move 1-byte overflow check to out_AbsByte 
This check is already performed in bulk by all functions calling it except
`out_AbsByte`, adding extra overhead to those.

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)

1d78cd0f03 Axe the constexpr expression evaluator

cc59730c5b Cleanup the RPN evaluator somewhat 
Make the bool field an actual bool

comments)

0a04904b75 Refactor RPN binary expressions into a single func

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.

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.
