Title: Fixes #14185 (regex! is generating unused code warnings)

This fix suppresses dead_code warnings from code generated by regex! when
the result of regex! is unused. Correct behavior should be a single
unused variable warning.

Regression tests are included for both `let` and `static` bound regex!
values.
