gfortran.h (gfc_option_t): Replace dump_parse_tree by dump_fortran_original and add dump_fortran_optimized.

2010-10-30  Thomas Koenig  <tkoenig@gcc.gnu.org>

	* gfortran.h (gfc_option_t):  Replace dump_parse_tree by
	dump_fortran_original and add dump_fortran_optimized.
	* lang.opt: Add fdump-fortran-original and
	fdump-fortran-optimized.  Document that fdump-parse-tree is
	deprecated.
	* gfortran.texi: Add -fdump-fortran-original and
	-fdump-fortran-optimized.  -fdump-parse-tree is deprecated.
	* frontend-passes.c (gfc_run_passes):  If optimizing and
	if gfc_option.dump_fortran_optimized is set, dump the parse tree
	after optimization.
	* parse.c:  Rename gfc_option.dump_parse_tree to
	gfc_option.dump_fortran_original.
	* options.c (gfc_init_options):  Rename gfc_option.dump_parse_tree
	to gfc_option.dump_fortran_original and handle
	gfc_option.dump_fortran_optimize.
	(gfc_post_options): Rename gfc_option.dump_parse_tree
	to gfc_option.dump_fortran_original.
	(gfc_handle_option):  Rename OPT_fdump_parse_tree to
	OPT_fdump_fortran_original and gfc_option.dump_parse_tree
	to gfc_option.dump_fortran_original.  Handle
	OPT_fdump_fortran_optimized.
