      [torque] uniform flattening and string access in Torque · 65d2c4b4
      Tobias Tebbi authored
      Port String::Flatten to Torque (using a fast C call for the
      non-allocating part) and provide fast and easy access to sequential
      string data in Torque: GetStringData() flattens if necessary and
      computes slices that allow direct access.
      
      Applications: String.prototype.replaceAll, String.prototype.endsWith,
        and String.prototype.beginsWith now use GetStringData() and direct
        slice access instead of the slow StringCharCodeAt and they no
        longer bail out to the runtime for flattening.
      
      Drive-by changes:
        - Expose String instance type bits as bitfields and enums in Torque.
        - Fix method lookup in Torque to include superclass methods.
        - Use char8 and char16 types in more places.
        - Allow fast C calls with void return type.
        - Add Torque macros to create subslices.
        - Add no-GC scopes to runtime functions loading external string data.
