Verbose mode for bench

[pjljvandelaar]

Recently, I upgrade from stack 1.9.3 to 2.1.1.
When I run stack bench on my project (see TorXakis/TorXakis#872)
I get Benchmark bench: ERROR in a unpredictable way.
This minimal information is unsufficient for me to determine
whether the fault is in my code (and only now detected by the new stack version) or
is a regression issue in stack.

I would like to turn on verbose to get more information on this error.
What went wrong? Did the program crash, or did stack have problems?

Note -v flag gives not more info:
