* [test][tools] Add missing and improve testingJames Henderson2019-12-091-0/+5
| | | | | | | | | | | Mostly this adds testing for certain aliases in more explicit ways. There are also a few tidy-ups, and additions of missing testing, where the feature was either not tested at all, or not tested explicitly and sufficiently.

* [llvm-symbolizer] Improve compatibility of --functions with GNU addr2lineJames Henderson2019-01-231-0/+109
This fixes https://bugs.llvm.org/show_bug.cgi?id=40072. GNU addr2line's --functions switch is off by default, has a short alias of -f, and does not take an argument. This patch changes llvm-symbolizer to allow the second and third point (changing the default behaviour may have negative impacts on users). If the option is missing a value, it now treats it as "linkage". This change does cause one previously valid command-line to behave differently. Before --functions <value> was accepted, but now only --functions=<value> is allowed (as well as --functions). The old behaviour will result in the value being treated as a positional argument. The previous testing for --functions=short has been pulled out into a new test that also tests the other accepted values and option formats.
