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.
