  * Change standard suffixes  .hi   and .o
      for tracing, to         .T_hi and .T_o
      for heap profiling, to  .hi   and .p_o
      for time profiling, to  .hi   and .t_o
    Both the compiler and hmake can now deal with these suffixes.
    There is now no need for a separate directory to hold the tracing
      versions of the .hi files for prelude and standard libraries.
    Build-dependencies are now more accurate, because the .hi files
      don't have to be removed and re-generated for tracing.
