gdb: Add 'tui reg prev' command.
There is already a 'tui reg next' command, this adds a symmetric 'tui
reg prev' command.
gdb/ChangeLog:
* tui/tui-regs.c (tui_reg_prev_command): New function.
(_initialize_tui_regs): Add 'prev' command for 'tui reg'.
* reggroups.c (reggroup_prev): New function.
* reggroups.h (reggroup_prev): Add declaration. Update comment.
gdb/doc/ChangeLog:
* gdb.texinfo (TUI Commands): Add 'tui reg prev' details.
