[v8,00/17] Improve generic string routines

  Changes since v7:
  - Split string-fzc.h out of string-fzi.h, with all of the
    routines that are combinations of fza and fzi routines.
  - Fix missing find_t and shift_find() from alpha, arm, powerpc.
  - Use compiler builtins for arm and powerpc.
  - Define sh4 has_zero() via has_eq(), rather than reverse.
