FPRow: Remove three unused methods

This fixes warnings from the Intel compiler:

    src/textord/cjkpitch.cpp(319): warning #177:
      function "<unnamed>::FPRow::good_gaps" was declared but never referenced
    src/textord/cjkpitch.cpp(383): warning #177:
      function "<unnamed>::FPRow::is_bad" was declared but never referenced
    src/textord/cjkpitch.cpp(387): warning #177:
      function "<unnamed>::FPRow::is_unknown" was declared but never referenced
