…ctly

long double (i.e. f128) is special-case in the sparc abi
there's no need to wrap the value at runtime to visit it
- fix margins
- ensure the MIR code wraps instead of needing scrollbars
- defocus the trace suffixes
This updates the rust-version file to da51146.
This updates the rust-version file to 32d94cc.
This reverts commit 102f03d2c410660a45d0231fdafdd347e0d4e77f.
Update unicode_data to Unicode version 18.0.0

Had to add an extra array to `L2Lut` to account for characters that change plane when case-mapped (so far, only U+1DF95 LATIN SMALL LIGATURE LONG S WITH DESCENDER S).

Also made `version()` defer to `ucd_parse::ucd_directory_version()`, which is more robust to minor changes in the ReadMe.txt format.

Use niche length type for strlen to guarantee `isize::MAX` bound

Alternative to rust-lang#162912.
