* symtab.c (decode_line_1): Use end of block to figure out whether

	val.end is in the same function, not minimal symbols.

	* source.c (line_info): Add a few more wrap_here's.

	* i386-tdep.c (i386_follow_jump): Do byteswapping where needed and
	don't make assumptions about sizes of host data types.

	* blockframe.c, symtab.h (find_pc_partial_function): New arg endaddr.
	* infrun.c, breakpoint.c, printcmd.c: Change callers.
	* printcmd.c (containing_function_bounds): Remove.
	* printcmd.c (disassemble_command): Use find_pc_partial_function,
	not containing_function_bounds.
	* infcmd.c (step_1): Use find_pc_partial_function rather than
	trying to roll our own.  Move check for a pc between SIGTRAMP_START and
	SIGTRAMP_END in find_pc_partial_function, not step_1.
