Refactor lexing of fixed-point numbers ( #1915 )
...
This incidentally fixes a bug with too-long fixed-point literals
that have precision suffixes.

Fix some fixed-point literal lexing issues ( #1914 )
...
- No fractional digits are necessary after the decimal point,
e.g. `42.` is valid instead of `42.0`
- Error messages refer to "fixed-point" not "integer" constants
- Test more carefully for lexing unrelated to underscores

Use loops instead of tail calls and musttail
...
gcc 15.2.1 20250813 complains "address of automatic variable can
escape to `musttail` call" from `-Wmaybe-musttail-local-addr`,
and guaranteeing tail-call optimization cross-platform is more
trouble than it's worth.
