blis/bench/bench_ger.c
Rayan, Rohan 979b547876 Make all bench applications consistent (#189) 
Lots of the bench applications were not taking n_repeats as an argument on the command line (while others were).
Also adding the feature to skip the rest of the line (at the end) while reading bench inputs for all APIs
