Can't use --profile and --benchmark-arguments simultaneously. #1772

When I run the following command my benchmark suite runs with profiling enabled (except for the issue I reported in #1771):

% stack bench --profile 

When I run this command my benchmark runs without profiling (as it should), and the argument is passed to Critierion to select a subset of the tests:

% stack bench --benchmark-arguments='theo1'

But when I try to combine them both I get an error:

% stack bench --profile --benchmark-arguments='theo1'

Good catch! +RTS options were not being terminated with -RTS. Please reopen if not fixed in HEAD.

I can confirm that the following command no longer gets an error:

 stack bench --profile --benchmark-arguments='theo1'

It also produces the profile report file, and that profile reports on cost centers from my library component. There's some residual weirdness, but not within the scope of this ticket.
