Simon Marchi 1be99b11f8 gdb: add cmd_list_element::is_alias ...

Add the cmd_list_element::is_alias helper to check whether a command is
an alias.  I find it easier to understand the intention in:

  if (c->is_alias ())

than

  if (c->alias_target != nullptr)

Change all the spots that are reading alias_target just to compare it to
NULL/nullptr to use is_alias instead.

gdb/ChangeLog:

	* cli/cli-decode.h (cmd_list_element) <is_alias>: New, use it.
