2706f94788 Multiple fixes and enhancements to RPN behavior: (#1448)
- FIX: `Label & const` was not actually doing the `& const` masking
  (fixes #1446)
- ADD: `LOW(Label)` can be constant if `Label` is aligned to 8 or more bits
  (resolves #1444)
- ADD: `!expr` can be constant 0 if `expr` has any non-zero bits
  (resolves #1447)
- `LOW()` and `HIGH()` have their own RPN operator values
  (resolves #1445)

The change to RPN values means that the object file version was incremented.

This also refactors unary operators and functions, combining their
evaluation similarly to binary ones.

39e9315e8a Use a smaller size for the lexer buffer
Large sizes are more efficient when it's actually buffered,
but most of the time `mmap` is used instead, and the extra size
just slows down allocation of lexer states.

9ab3446d1a Fix two bugs with RGBASM fixed-point math (#1388)
- Fixed-point formulas are implemented using IEEE-754 floating-point
  internally, which could give infinity or NaN values whose conversion
  to fixed-point integer was platform-dependent.
- Formatting fixed-point $8000_0000 (INT32_MIN, -2147483648) was
  not putting the negative sign in front.
