Refactor the code in the `convert_while_ascii` helper function to make it more suitable for auto-vectorization and also process the full ascii prefix of the string. The generic case conversion logic will only be invoked starting from the first non-ascii character. The runtime on microbenchmarks with ascii-only inputs improves between 1.5x for short and 4x for long inputs on x86_64 and aarch64. The new implementation also encapsulates all unsafe inside the `convert_while_ascii` function. Fixes #123712 |
