* disasm.c (gdb_print_insn): Return the number of branch delay
slot instructions too.
* disasm.h (gdb_print_insn): Update prototype.
* printcmd.c (branch_delay_insns): New variable to record the
number of delay slot instructions after disassembling a branch.
(print_formatted): Record the number of branch delay slot
instructions.
(do_examine): When disassembling, if the last instruction
disassembled has any branch delay slots, then bump the count so
that they get disassembled too.
* tui/tui-disasm.c (tui_disassemble): Update the call to
gdb_print_insn().
* NEWS: Document the new behaviour.

gdb/doc/:
* gdb.texinfo (Examining Memory): Document the new behaviour.

gdb/gdbtk/:
* generic/gdbtk-cmds.c (gdbtk_load_asm): Update the call to
gdb_print_insn().
