Description
Several of the string/regex algorithms methods in the _StringProcessing module take throwing closures and are marked as rethrows. They should be converted to typed throws while maintaining the existing ABI.
In addition, trimPrefix was published marked as throws instead of rethrows, so that will need some additional consideration to avoid source breakage.

Research direction
Start by locating the _StringProcessing module and its string/regex algorithm methods that accept throwing closures, then review their existing ABI and rethrows declarations. Verify that the conversions preserve the existing ABI and source behavior, with particular attention to the published trimPrefix method and its throws declaration.
