Add support for prefix-only CLI options

Authored by thopre on Jan 10 2019, 7:46 AM.



Add support for options that always prefix their value, giving an error
if the value is in the next argument or if the option is given a value
assignment (ie. opt=val). This is the desired behavior for the -D option
of FileCheck for instance.

Fix comment in LookupOption for AlwaysPrefix early bail out

Clarify what happens in LookupOption when failing to match an option.

I commented when this was part of D55940. However, I'm not as familiar with this area, especially the unit testing, so someone else should review further.

Nice work on the prefix tests. One comment nit and LGTM.
