Reviewer's Guide

Adds end-to-end native execution tests for the string functions bit_length, longest_common_prefix, and replace_first within the existing string functions test suite.

File-Level Changes

Change	Details	Files
Extend native worker string function E2E test coverage to include bit_length, longest_common_prefix, and replace_first with both generic and edge-case assertions.	Add bit_length queries over nation.name and orders.comment plus explicit empty-string and literal cases with expected bit lengths Add longest_common_prefix queries over nation.name and orders.comment plus explicit empty-string and partial-prefix literal cases with expected prefixes Add replace_first queries over orders.comment and nation.name plus literal replacement cases including repeated characters and whitespace removal	presto-native-execution/src/test/java/com/facebook/presto/nativeworker/AbstractTestNativeGeneralQueries.java

Hey - I've left some high level feedback:

• For the tests that only exercise scalar behavior with literals (e.g., bit_length(''), longest_common_prefix('', ''), replace_first('aaa', 'a', 'b')), consider using VALUES instead of FROM nation to avoid unnecessary table scans and keep the E2E suite leaner.
• The new SELECT ... FROM orders/nation assertions without LIMIT (e.g., bit_length(comment), replace_first(comment, 'the', 'THE')) will compare full table results between engines; if the intent is just to exercise the function end-to-end, you might want to narrow these (e.g., with LIMIT or a restricted predicate) to reduce test runtime.

Please address the comments from this code review:

## Overall Comments
- For the tests that only exercise scalar behavior with literals (e.g., `bit_length('')`, `longest_common_prefix('', '')`, `replace_first('aaa', 'a', 'b')`), consider using `VALUES` instead of `FROM nation` to avoid unnecessary table scans and keep the E2E suite leaner.
- The new `SELECT ... FROM orders/nation` assertions without `LIMIT` (e.g., `bit_length(comment)`, `replace_first(comment, 'the', 'THE')`) will compare full table results between engines; if the intent is just to exercise the function end-to-end, you might want to narrow these (e.g., with `LIMIT` or a restricted predicate) to reduce test runtime.
