Raphael Isemann aaf68cd9ce [lldb] Warn the user about starting the --func-regex parameter with an asterisk ... Summary: Sometimes users think that setting a function regex for all function that contain the word 'needle' in their name looks like this: `*needle*`. However, LLDB only searches the function name and doesn't fully match it against the regex, so the leading and trailing '*' operators don't do anything and actually just cause the regex engine to reject the regular expression with "repetition-operator operand invalid". This patch makes this a bit more obvious to the user by printing a warning that a leading '*' before this regular expression here doesn't have any purpose (and will cause an error). This doesn't attempt to detect a case where there is only a trailing '*' as that would involve parsing the regex and it seems the most common way to end up in this situation is by doing `rbreak *needle*`.
