taco-tool: the benchmark utility of the taco tool no longer works

[rohany]

If you attempt to benchmark programs with the taco-tool, i.e. specifying formats, data and -time=5, the program fails with a generated code compilation error.

pinging @Infinoid because I think you were the last person to touch the code around this area, based on git blame.

I believe this bug should actually be fixed in the eval_at_assign branch. Can you check if that's the case?

I see this error now:

test-mat.mtx is just a small mtx file.

Commit 823e8da works fine for me, so I'm not sure what's going on:

stephenchouca@DESKTOP-9ANRGV7:~/taco/build$ ./bin/taco "a(i) = B(i, j) * c(i)" -f=a:d -f=B:ds -f=c:d -g=c:d -time=5 -i=B:cage3/cage3.mtx

Ah I think I didn't rebuild properly. It works for me now. Let me see what I can pull in from the commit to fix the issue on my branch.
