[commtech] Use only 1 thread per core
...
Creating 2 thread per core in the purpose of receiving while sending is
plain stupid. First it needs 2 threads synchronizing with each other
which has a cost. Second, since only one thread can run at a time the
threads slow each other (using BatchQueue where the sender is on the
same core as the receiver yields bad performance). This patch remove all
this complexity to have one thread receive, compute and then resend
data, which improve performances dramatically.

parsing.sh: Remove assumption about calc args
...
Calc can have several args for useless_loop and line prods and for comm
and barriere bench. Hence:
* Change use_histo to reflect that
* Set list of args per bench/prod instead of globally
* No need for the argument (since there is several) in create_complex_dat_body
