PR bootstrap/17761
* lcm.c (optimize_mode_switching): Update to use EDGE_SUCC and
FOR_EACH_EDGE macros.

From-SVN: r88368

Simplify lexer.  Implement --enable-mapped-location support.

* jcf-parse.c (parse_class_file):  Use linemap_line_start.
(parse_source_file_1): Pass filename as extra parameter, so we can call
linemap_add and set input_location here, rather than in both callers.
(read_class): Pass copied filename to parse_source_file_1.
Don't initialize wfl_operator - only needed for source compilation.
(read_class, jcf_parse):  Call linemap_add with LC_LEAVE.
* lex.h:  Remove a bunch of debugging macros.
* lex.h (struct_java_line, struct java_error):  Remove types.
(JAVA_COLUMN_DELTA):  Remove - use java_lexer.next_colums instead.
(struct java_lc_s):  Remove prev_col field.
(struct java_lexer):  New fields next_unicode, next_columns, and
avail_unicode.  New position field, and maybe token_start field.
Don't need hit_eof field - use next_unicode == -1 instead.
(JAVA_INTEGERAL_RANGE_ERROR):  Rename to JAVA_RANGE_ERROR.
(JAVA_RANGE_ERROR, JAVA_FLOAT_ANGE_ERROR):  Update accordingly.
* parse.h:  Various changes for USE_MAPPED_LOCATION.

(struct parser_ctxt):  New file_start_location field.
Remove p_line, c_line fields since we no longer save lines.
Remove elc, lineno, and current_jcf fields - no longer used.
* parse.y:  Updates for USE_MAPPED_LOCATION and new lexer.
Don't use EXPR_WFL_ADD_COL since that isn't trivial with
source_location and is probably not needed anymore anyway.
Use new expr_add_Location function.
(SET_EXPR_LOCATION_FROM_TOKEN):  New convenience macro.
(java_pop_parser_context):  Minor cleanup.

(fix_constructors): Make more robust if no EXPR_WITH_FILE_LOCATION.

Use IS_A_COMMAND_LINE_FILENAME_P to check for duplicate filenames.
Create a list of TRANSLATION_UNIT_DECL.
(current_file_list):  Is now a TRANSLATION_UNIT_DECL chain.  The
reason is so we can set a DECL_SOURCE_LOCATION for each file.
(java_parse_file):  Don't set unused ZIP_FILE_P, JAVA_FILE_P..
Create line-map LC_ENTER/LC_LEAVE entries for archive itself.
