* Makefile.in (STAGESTUFF): Wildcard all debugging dumps at once.
(mostlyclean): Likewise.
* toplev.c (rtl_dump, jump_opt_dump, etc): Remove.
(struct dump_file_info, enum dump_file_index, dump_file): New.
(open_dump_file): Take a dump_file_index not a suffix, and a decl
not a string. Clean out file if we havn't yet done so. Do nothing
if the dump isn't enabled.
(close_dump_file): Do nothing if the dump isn't open. Dump
graph data if requested.
(dump_rtl, clean_dump_file): Remove.
(compile_file): Don't clean the dump files. Only finalize .bp dump
if flag_test_coverage or flag_branch_probabilities. Only finalize
.combine dump if optimizing. Iterate over dump_file to finalize the
graph dumps.
(rest_of_compilation): Update for open_dump_file/close_dump_file.
Convert all uses of dump_rtl.
(decode_d_option): Iterate over dump_file to implement 'a' and to
locate pass-specific dumps.
