Added a gcc preprocessor options -P, -P1

tcc -E -P
  do not output a #line directive, a gcc compatible option

tcc -E -P1
  don't follow a gcc preprocessor style and do output a standard
  #line directive. In such case we don't lose a location info when
  we going to compile a resulting file wtith a compiler not
  understanding a gnu style line info.
