Speed up GDB startup time by not demangling partial symbols.

* symfile.h (ADD_PSYMBOL_VT_TO_LIST),
	symfile.c (add_psymbol_to_list, add_psymbol_addr_to_list):
	No longer demangle partial symbols.
	* symtab.c (lookup_symbol, list_symbols): Handle mangled
	variables, e.g. C++ static members, via the minimal symbols.

	Handle reordered functions in an objfile, for Irix 5.2 shared
	libraries.
	* objfiles.h (OBJF_REORDERED):  New bit in the objfile flags,
	set if the functions in an objfile are reordered.
	* mdebugread.c (parse_partial_symbols):  Detect reordered
	functions in an objfile.
	* symtab.c (find_pc_psymtab, find_pc_symtab):  Use expensive
	lookup algorithm if the functions in the objfile are reordered.

	* xcoffexec.c (exec_close):  If the current target has a copy
	of the exec_ops sections, reflect the freeing of the sections
	in current_target.

	* valops.c (call_function_by_hand):  Use `sizeof dummy1', not
	`sizeof dummy', for constructing the call dummy code.

	* config/sparc/tm-sparc.h:  Add PARAMS declarations to all
	function declarations.
	* sparc-tdep.c (sparc_pop_frame):  Cast result of
	read_memory_integer to CORE_ADDR when passing it to PC_ADJUST.

	* irix5-nat.c (enable_break):  Set breakpoint at the entry point
	of the executable, to handle the case where main resides in a
	shared library.
	* irix5-nat.c (solib_create_inferior_hook):  Reset stop_soon_quietly
	after shared library symbol reading, to get rid of a warning from
	heuristic_proc_start if the startup code has no symbolic debug info.

	* breakpoint.h (struct breakpoint):  Add new fields language
	and input_radix, to enable breakpoint resetting with the
	proper language and radix.
	* breakpoint.c (set_raw_breakpoint):  Initialize them.
	(breakpoint_re_set_one):  Use them when resetting the breakpoint.
	(breakpoint_re_set):  Preserve current language and input_radix
	across breakpoint_re_set_one calls.

	* symtab.c (decode_line_1):  Do not build a canonical line
	specification for `*expr' line specifications.

	* breakpoint.h (bpstat_stop_status):  Fix prototype declaration.
