Decompose singular `matches!` with or-patterns to individual `matches!` statements to enable branchless code output. The following functions were changed: - `is_ascii_alphanumeric` - `is_ascii_hexdigit` - `is_ascii_punctuation` Add codegen tests Co-authored-by: George Bateman <george.bateman16@gmail.com> Co-authored-by: scottmcm <scottmcm@users.noreply.github.com>
